To save or restore an image

ocs-sr [OPTION] {savedisk|saveparts|restoredisk|restoreparts} IMAGE DEVICE

IMAGE is the image dir name in /home/partimag, not absolute path

DEVICE name can be with or without /dev/, e.g., /dev/sda or sda.

When in saving mode, the DEVICE name can also be assigned by:

For disk: PTUUID or SERIALNO (short format), e.g., PTUUID=03c8b280-47aa-4881-aca5-9b9c66fe28c7.

For partition: UUID or PARTUUID, e.g., UUID=0b51ce79-7bc0-4111-8a40-839461a9b12f

When in resotoring mode, the DEVICE name can also be assigned by (for disk only):

SERIALNO (short format), e.g., SERIALNO=2YK8XSYD.

If there are spaces in SERIALNO, replace every space by "_"

Options for saving:

-noabo, --not-only-access-by-owner Make the image of partition can be accessed by others, not only by owner. By default the image of partition will be changed as 600. With this option, it will be 644.

-senc, --skip-enc-ocs-img Skip encrypting the image with passphrase.

-enc, --enc-ocs-img To encrypt the image with passphrase.

-sfsck, --skip-fsck-src-part Skip running fsck on the source file system before saving it.

-fsck, -fsck-src-part, --fsck-src-part Run fsck interactively on the source file system before saving it.

-fsck-y, -fsck-src-part-y, --fsck-src-part-y Run fsck automatically on the source file system before saving it. This option will always attempt to fix any detected filesystem corruption automatically. //NOTE// Use this option in caution.

-gm, --gen-md5sum Generate the MD5 checksum for the image. Later you can use -cm|--check-md5sum option to check the image when restoring the image. Note! It might take a lot of time to generate if the image size is large.

-gs, --gen-sha1sum Generate the SHA1 checksum for the image. Later you can use -cs|--check-sha1sum option to check the image when restoring the image. Note! It might take a lot of time to generate if the image size is large.

-gmf, --gen-chksum-for-files-in-dev Generate the checksum for files in the source device. Later you can use -cmf|--chk-chksum-for-files-in-dev to check the files in the destination device after they are restored. Note! It might take a lot of time to inspect the checksum if there are many files in the destination device.

-i, --image-size SIZE Set the size in MB to split the partition image file into multiple volumes files. For the FAT32 image repository, the SIZE should not be larger than 4096.

-j2, --clone-hidden-data Use dd to clone the image of the data between MBR (1st sector, i.e. 512 bytes) and 1st partition, which might be useful for some recovery tool.

-ntfs-ok, --ntfs-ok Assume the NTFS integrity is OK, do NOT check again (for ntfsclone only)

-rm-win-swap-hib, --rm-win-swap-hib Try to remove the MS windows swap file in the source partition.

-q, --use-ntfsclone If the partition to be saved is NTFS, use program ntfsclone instead of partimage (i.e. Priority: ntfsclone > partimage > dd)

-q1, --force-to-use-dd Force to use dd to save partition(s) (inefficient method, very slow, but works for all the file system).

-q2, --use-partclone Use partclone to save partition(s) (i.e. partclone > partimage > dd).

-rescue, --rescue Turn on rescue mode, i.e. try to skip bad sectors.

-sc, -scs, --skip-check-restorable, --skip-check-restorable-s By default Clonezilla will check the image if restorable after it is created. This option allows you to skip that.

-z0, --no-compress Don't compress when saving: very fast but very big image file (NOT compatible with multicast restoring!!!)

-z1, --gzip-compress Compress using gzip when saving: fast and small image file (default)

-z1p, --smp-gzip-compress Compress using parallel gzip program (pigz) when saving: fast and small image file, good for multi-core or multi-CPU machine

-z2, --bz2-compress Compress using bzip2 when saving: slow but smallest image file

-z2p, --smp-bzip2-compress Compress using parallel bzip2 program (lbzip2) when saving: faster and smallest image file, good for multi-core or multi-CPU machine

-z3, --lzo-compress Compress using lzop when saving: similar to the size by gzip, but faster than gzip.

-z4, --lzma-compress Compress using lzma when saving: slow but smallest image file, faster decompression than bzip2.

-z5, --xz-compress Compress using xz when saving: slow but smallest image file, faster decompression than bzip2.

-z5p, --smp-xz-compress Compress using parallel xz when saving: slow but smallest image file, faster decompression than bzip2.

-z6, --lzip-compress Compress using lzip when saving: slow but smallest image file, faster decompression than bzip2.

-z6p, --smp-lzip-compress Compress using parallel lzip when saving: slow but smallest image file, faster decompression than bzip2.

-z7, --lrzip-compress Compress using lrzip when saving.

-z8, --lz4-compress Compress using lz4 when saving.

-z8p, --lz4mt-compress Compress using lz4mt when saving.

-z9, --zstd-compress Compress using zstd when saving.

-z9p, --zstdmt-compress Compress using zstdmt when saving.

-i, --image-size SIZE Set the split image file volume size SIZE (MB). When ocs-sr is run with -x, the default SIZE is set as 0, if without -x, we will not split it.

-sfs, --skip-fs-save Do not save the file system for device, just save the rest of files. This is mainly for BT from device massive deployment. A tag file 00-pseudo-img-note.txt will be added in the image dir, too.

-pe, --passwd-ecryptfs PASSWD Set the password to encrypt the image. Use with option "-enc" when saving, or restoring when the image is encrypted. //NOTE// This is not a safe way to use it because the password is shown in the command line or system processes.

-pfe, --passwd-file-ecryptfs FILE Set the password to encrypt the image in the FILE. Use with option -enc, or restoring when the image is encrypted. The file contains the password to encrypt the image. Its format is like: passphrase_passwd=YOURPASSWORD.

-scpt, --skip-check-part-table Skip checking the partition table of the source disk, i.e., just save it without checking it is MBR or GPT format.

-luks, --enable-luks MODE Open LUKS device or not. MODE can be either yes or no.

Some words are reserved for IMAGE_NAME, "ask_user" is used to let user to input a name when saving an image. "autoname" is used to automatically generate the image name based on network card MAC address and time. "autohostname" is used to automatically generate the image name based on hostname. "autoproductname" is used to automatically generate the image name based on hardware product model gotten from dmidecode.

The words reserved for DEVICE: "ask_user" could be used to let user to select the source device when saving an image. "all" can be used for all the unmounted local disks or partitions, depending on the mode is to save disks or partitions.

Options for restoring:

-f, --from-part PARTITION Restore the partition from image or block device. This is especially for "restoreparts" to restore the image of partition (only works for one) to different partition, e.g. sda1 of image to sdb6, or partition to partition, e.g, sda1 to sdb2.

-g, --grub-install GRUB_PARTITION Install grub in the MBR of the disk containing partition GRUB_PARTITION with root grub directory in the same GRUB_PARTITION when restoration finishes, GRUB_PARTITION can be one of "/dev/sda1", "/dev/sda2"... or "auto" ("auto" will let clonezilla detect the grub root partition automatically). If "auto" is assigned, it will work if grub partition and root partition are not in the same partition.

-r, --resize-partition Resize the partition when restoration finishes, this will resize the file system size to fit the partition size. It is normally used when when a small partition image is restored to a larger partition.

-k, --no-fdisk, --no-create-partition Do NOT create partition in target harddisk. If this option is set, you must make sure there is an existing partition table in the current restored harddisk. Default is to create the partition table.

-icrc, --icrc Skip Partclone CRC checking.

-irhr, --irhr Skip removing the Linux udev hardware records on the restored GNU/Linux.

-irvd, --irvd Skip removing the NTFS volume dirty flag after the file system is restored.

-ius, --ius Skip updating syslinux-related files on the restored GNU/Linux.

-iui, --iui Skip updating initramfs file(s) on the restored GNU/Linux.

-icds, --ignore-chk-dsk-size-pt Skip checking destination disk size before creating the partition table on it. By default it will be checked and if the size is smaller than the source disk, quit.

-iefi, --ignore-update-efi-nvram Skip updating boot entries in EFI NVRAM after restoring.

-k0, Create partition table based on the partition table from the image. this is the same as as default. Just an option to let us explain the action easier.

-k1, Create partition table in the target disk proportionally.

-k2, Enter command line prompt to create partition table manually before restoring image.

-scr, --skip-check-restorable-r By default Clonezilla will check the image if restorable before restoring. This option allows you to skip that.

-t, --no-restore-mbr Do NOT restore the MBR (Mater Boot Record) when restoring image. If this option is set, you must make sure there is an existing MBR in the current restored harddisk. Default is Yes

-t1, --restore-raw-mbr Restores the prebuilt bootloader from syslinux (For Windows only)

-t2, --no-restore-ebr Do NOT restore the EBR (Extended Boot Record) when restoring image. Default is to restore

-u, --select-img-in-client Input the image name in clients

-e, --load-geometry Force to use the saved CHS (cylinders, heads, sectors) when using sfdisk

-e1, --change-geometry NTFS-BOOT-PARTITION Force to change the CHS (cylinders, heads, sectors) value of NTFS boot partition after image is restored. NTFS-BOOT-PARTITION can be one of "/dev/sda1", "/dev/sda2"... or "auto" ("auto" will let clonezilla detect the NTFS boot partition automatically)

-e2, --load-geometry-from-edd Force to use the CHS (cylinders, heads, sectors) from EDD (Enhanced Disk Device) when creating partition table by sfdisk

-j, --create-part-by-sfdisk Use sfdisk to create partition table instead of using dd to dump the partition table from saved image (This is default)

-j0, --create-part-by-dd Use dd to dump the partition table from saved image instead of sfdisk. ///Note/// This does NOT work when logical drives exist.

-j1, --dump-mbr-in-the-end Use dd to dump the MBR (total 512 bytes, i.e. 446 bytes (executable code area) + 64 bytes (table of primary partitions) + 2 bytes (MBR signature; # 0xAA55) = 512 bytes) after disk image was restored. This is an insurance for some hard drive has different numbers of cylinder, head and sector between image was saved and restored.

-j2, --clone-hidden-data Use dd to clone the image of the data between MBR (1st sector, i.e. 512 bytes) and 1st partition, which might be useful for some recovery tool. When this option is used, it only works for restoredisk mode, not the restoreparts one

-hn0 PREFIX Change the hostname of MS Windows based on the combination of hostname prefix and IP address, i.e. PREFIX-IP

-hn1 PREFIX Change the hostname of MS Windows based on the combination of hostname prefix and NIC MAC address, i.e. PREFIX-MAC

--max-time-to-wait TIME When not enough clients have connected (but at least one), start anyways when TIME seconds since first client connection have pased. This option is used with --clients-to-wait

-cm, --check-md5sum Check the MD5 checksum for the image. To use this option, you must enable -gm|--gen-md5sum option when the image is saved. Note! It might take a lot of time to check if the image size is large.

-cs, --check-sha1sum Check the SHA1 checksum for the image. To use this option, you must enable -gs|--gen-sha1sum option when the image is saved. Note! It might take a lot of time to check if the image size is large.

-cmf, --chk-chksum-for-files-in-dev Check the checksum for the files in the device. To use this option, you must enable -gmf|--gen-chksum-for-files-in-dev when the image is saved. Note! (1) The file system must be supported by Linux kernel so that it can be mounted as read-only to check the files. (2) It might take a lot of time to check if there are many files in the source device.

-srel, --save-restore-error-log Save the error log file in the image dir. By default the log file won't be saved when error occurs.

--mcast-port NO Assign the udp port number for multicast restore. This is used by clonezilla server. Normally it's not necessary to manually assign this option.

-ssnf, --skip-set-netboot-first Skip setting 1st boot device as network in uEFI NVRAM of the restored machine.

Some words are reserved for IMAGE_NAME, "ask_user" is used to let user to input a name when saving an image. "autoproductname" is used to automatically get the image name based on hardware product model from dmidecode.

A word is reserved for DEVICE, "ask_user" could be used to let user to select the source device when saving an image.

General options:

-l, --language INDEX Set the language to be shown by index number:

[0|en_US.UTF-8]: English,

[2|zh_TW.UTF-8]: Traditional Chinese (UTF-8, Unicode) - Taiwan

[a|ask]: Prompt to ask the language index

This option is for backward compatibility. It's recommended to use locales to assign that.

-b, -batch, --batch (DANGEROUS!) Run program in batch mode, i.e. without any prompt or wait for pressing enter key. //NOTE// You have to use '-batch' instead of '-b' when you want to use it in the boot parameters. Otherwise the program init on system will honor '-b', too.

-c, --confirm Wait for confirmation before saving or restoring

-d, --debug-mode Enter command mode to debug before saving/restoring

--debug=LEVEL Output the partimage debug log in directory /var/log/ with debug LEVEL (0,1,2... default=0)

-m, --module MODULE Force to load kernel module MODULE, this is useful when some SCSI device is not detected. NOTE! Use only one module, more than one may cause parsing problem.

--use-netcat Use netcat instead of nuttcp when running ocs-onthefly in the clone over net mode.

--net-filter PROGRAM Use the PROGRAM (gzip/lzop/bzip2/xz/lz4/zstd/cat) before sending partition data to netcat (only in network clone mode). The default action is zstd. Use "cat" if you do not want to compress (Good for fast internode network).

-o0, --run-prerun-dir Run the script in the directory /usr/share/drbl/postrun/ocs/ before clone is started. The command will be run before MBR is created or saved.

-o1, -o, --run-postrun-dir Run the script in the directory /usr/share/drbl/postrun/ocs/ when clone is finished. The command will be run before that assigned in -p or --postaction.

-w, --wait-time TIME Wait for TIME secs before saving/restoring

-nogui, --nogui Do not show GUI (TUI) of Partclone or Partimage, use text only

-a, --no-force-dma-on Do not force to turn on HD DMA

-mp, --mount-point MOUNT_POINT Use NFS to mount MOUNT_POINT as directory ocsroot (ocsroot is assigned in drbl.conf)

-or, --ocsroot DIR Specify DIR (absolute path) as directory ocsroot (i.e. overwrite the ocsroot assigned in drbl.conf)

-p, --postaction [choose|poweroff|reboot|command|CMD] When save/restoration finishes, choose action in the client, poweroff, reboot (default), in command prompt or run CMD

-ps, --play-sound Play sound when the job is done.

-ns, --ntfs-progress-in-image-dir Save the ntfsclone progress tmp file in the image dir so that if cloning is in DRBL client, the progress can be check in the server (Default in to be put in local /tmp/, which is local tmpfs).

-s, --source-IP IPADD Assign the IP address of source machine for device to device cloning. This option is mainly used by ocs-onthefly to run ocs-sr in device to device cloning over net.

-bm, --beginner-mode Run in beginner mode. This is a short way for "-um beginner".

-em, --expert-mode Run in expert mode. This is a short way for "-um expert".

-um, --user-mode [beginner|expert] Specify the mode to use. If not specified, default mode is for a beginner.

-v, --verbose Prints verbose information

-d0, --dialog Use dialog

-d1, --Xdialog Use Xdialog

-d2, --whiptail Use whiptail

-d3, --gdialog Use gdialog

-d4, --kdialog Use kdialog

-x, --interactive Interactive mode to save or restore.

-os, --ocs-server SRV Assign the OCS server as SRV.

Example:

Before saving or restoring an image, you have to make sure the device is NOT mounted!

To save all the data in local 1st harddrive 'sda' as image 'IMAGE1', use ntfsclone, and lzop compression:

ocs-sr --use-ntfsclone -z3 savedisk IMAGE1 sda

To save the data in 1st and 2nd partition in local first harddrive 'sda' as image 'IMAGE2', use ntfsclone:

ocs-sr --use-ntfsclone -z3 saveparts IMAGE2 "sda1 sda2"

To restore the image IMAGE1 to local sda, and grub-install will be run after cloning:

ocs-sr -g auto restoredisk IMAGE1 sda

To restore the image for the 1st and 2nd partition from IMAGE2 to local sda1 and sda2, and grub-install will be run after restoring:

ocs-sr -g auto restoreparts IMAGE2 "sda1 sda2"

To save disk(s)/partition(s) as an image or restore an image to disk(s)/partition(s) interactively, use:
