LSM comes with a set pre-configured Clonezilla parameters, supported by LinMin .
We encourage you to further optimize your LSM Snapshots by trying Clonezilla parameters that may be beneficial in your specific environment.
If the parameters you try don't work for you, simply revert back to the default parameters.
The following parameters were extracted from the RAM Agent command line for clonezilla-live-20200428-focal-amd64:
# ocs-sr --help
Capture Snapshot Parameters:
-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 4096, if without -x, we will not split it.
-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.
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.
A word is reserved for DEVICE, "ask_user" could be used to let user to select the source device when saving an image.
