dbackup [GENERAL_OPTIONS] [--backup BACKUP_OPTIONS | --restore RESTORE_OPTIONS ] [SRC] [DST]

This is a backup software package which creates one archive per directory it backs up. This makes searching through the backup much easier as you can look for which files you're after in the directory hierarchy. It will only backup directories which have changed, which makes it rsync friendly.

--config FILE

Configuration file to use.

--log-level

5 = debug, 4 = info, 3 = notice, 2 = warning, 1 = error

--backup

Perform a backup operation.

--restore

Perform a restore operation.

--tar

Path to tar binary. This should almost never need to be specified, it is used to specify a different tar binary to use other than the default system binary. Some versions of tar used to have bugs preventing correct operation, this allowed specification of an alternative binary to use.

--manifest-format

Manifest format to use, currently the two supported formats is "null" for \0 (null) termination of entries or "newline" for \n (newline) termination of entries. This should not need to be overridden.

--help

Display commandline help.

--backup-upgrade

Upgrade backup to new dbackup version. This will cause all archives to be refreshed if they were generated with an older version of AWIT DBackup.

--compress <gzip|bzip2|xz|lz|none>

Compression method to use. Defaults to using xz, or bzip2 if xz is unavailable. Parallel versions of these Compression programs will be used if they exist. Here is the order compression programs are looked for: gzip = pigz > gzip, bzip2 = pbzip2 > lbzip2 > bzip2, xz = pxz > pixz > xz, lz = plzip > pdlzip > clzip.
