isnapshot - Incremental Backup Program

December 19, 2006

isnapshot performs incremental backups by copying changed files and symlinking unchanged files to a previous full backup. The result is an always available incremental backup with minimal wasted space.

It's meant to be run as a cron job or manually to create quick snapshots of working directories or to do full system backups.

su && make install
Then, add a cron job possibly like the following,
02 4 * * * root /usr/local/bin/isnapshot /home /var/www /etc /snapshot_dir
