App::sibs - Simple incremental backup system

0.15

sibs create backup from your computer to a destination server, using rsync.

• Setup

  First you need to setup sibs. The setup process will create a SSH key which is uploaded to the destination server. The key is created using ssh-keygen and uploaded using ssh and perl.

  In addition, this step will create or update a config file. The default config file is ".sibs.conf" in $HOME, but you can also specify your own path.

• Backup

  The second step will create the actual backup. This step can be automated in a cronjob, because the key created in the first step will not require any password to log into the remote backup server. Example crontab:

  0 */4 * * * /usr/local/bin/sibs backup 2>/dev/null 1>/dev/null

  This will create a backup every four hours. The backup will be "full" each time and kept for a month. Even so, it probably won't take up too much space, since all the files are hard linked, meaning an unchanged file will take up the same disk space for each backup.

$ sibs <action> <options> <config file>
$ sibs setup
$ sibs backup

• action: setup

  Used to set up the inital config file.

• action: backup

  Used to take backup.

• action: man

  Used to see this help text.

• options: --verbose, --silent

  Adjust log level.

• config file: Path to "CONFIG FILE".

The config file is in perl format, and read by perl. This means that any perl code that exists in the file will be evaluated by perl. The return value need to be a hash with the config. Example:

{
  format => '%d-%H', # default
  exclude => [qw( .cache .gvfs Downloads Dropbox Trash )],
  source => [qw( /home/username )],
  destination => "rsync://[email protected]/var/backup/username",
}

Defaults:

• format: %d-%H

  The "format" will name the destination folder. See "FORMAT" in POSIX::strftime::GNU for details.

• exclude: .cache, .gvfs, Downloads, Dropbox, Trash

  Which files/directories to exclude.

• source: $HOME

  Which directory to backup.

Default exclude may change in future release.
