Using these standard tools and a simple configuration file Cella provides a practical and simple method of backup.
Cella is just a PHP script, w/o any dependencies on other frameworks. Each of the Actions that Cella can perform depends on an outside tool. For example, to do an rdiff based backup the rdiff-package must be installed.
Installation is to simply download the script to the target system and make it executable.
user@host # mkdir -p /opt/edoceo/cella/ user@host # cd /opt/edoceo/cella/ user@host # wget edoceo.com/bin/cella.sh user@host # chmod 0755 cella.sh
Standard command format is
Here are some examples.
user@host # ./cella.sh
Show the Job List
user@host # ./cella.sh show
Run the Job List
user@host # ./cella.php pack
Run the Job List - debug/dry-run mode
user@host # ./cella.php -d pack
Show Archive List!
user@host # ./cella.php list
Do a few things (like in cron)
user@host # ./cella.php pack trim list
Cella scans the locations above for configuration files and loads each. Later files can/will over-write the data from the previous.
The files are plain ini style configurations. Section names are the titles of the backup job. The action, source and target parameters are required for all jobs.
