Clonezilla Backup and Restore imaging parameters were introduced with Cisco Server Provisioner Release 6.1 to address a wide range of options around file system types, partitioning, Master Boot Record (MBR) structures and more.

Please note that certain parameters only apply to Backup or to Restore. For example, the "-q2" backup option (to backup system with VMFS such as ESX, or Ext4) is required only for backup, to ensure the proper system is invoked to detect the file system type. During Restore, no explicit parameter is required.

Note: the following list of parameters applies to the entire Clonezilla system, most of which are implemented in the Provisioning Server. Many of these parameters are intended for use only with Clonezilla Live when using the "Live Ubuntu" Rescue System.

Backup Parameters

-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.

-sc                      Skip file system type checking (use for ESX or whenever the message "Broken partition images" appears on the client due to "dd" type partitions being backed up and checked). The image checking after saving is turned on by default.

-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 (pbzip2) 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.

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

-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).

-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.

-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 2000, if without -x, we will not split it

Restore Parameters

-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 finishs, GRUB_PARTITION can be one of "/dev/hda1", "/dev/hda2"... 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 try to fix the problem when small partition image is restored to larger partition. Warning!!! Use this carefully... Backup your data first

-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 Yes

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

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

-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

-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 partitoin after image is restored. NTFS-BOOT-PARTITION can be one of "/dev/hda1", "/dev/hda2"... 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

-y, -y0, --always-restore, --always-restore-default-local  Let Clonezilla server as restore server, i.e. client will always has restore mode to choose (However default mode in PXE menu is local boot)

-y1, --always-restore-default-clone Let Clonezilla server as restore server, i.e. client will always has restore mode to choose (The default mode in PXE menu is clone, so if client boots, it will enter clone always, i.e. clone forever)

-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.

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

-hn1 PREFIX     Change the hostname of M$ 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.

--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.

General Parameters
