  -c    path to non-default config file
  -v    verbose tarball extraction
  -s    source of backup, default is to read target from config
  -d    destination of restore, default is ./restore
  -l    number of incremental backup, default is latest

configuration items

mount

Single value. Optional.

Path to be mounted before backing up. Will be unmounted unless -n is specified.

target

Single value. Required.

This is the place where the tarballs will be located. Organized by year-month.

example:

/mnt/san/backup/2018-07/backup_0.tgz   # full backup tarball
/mnt/san/backup/2018-07/backup_0.snar  # full backup backup index
/mnt/san/backup/2018-07/backup_1.tgz   # incremental tarball
/mnt/san/backup/2018-07/backup_1.snar  # incremental backup index

This is organized so that each month there is a full backup, and every subsequent backup that month will be incremental

source

Multiple values.

Stuff to copy into the tarball. Files or directories.
