The combination of a full backup, and an archive of incremental backups can allow you to restore a choice of points in time. If you only want full data backup capability - the suggested daily backup utilities can do that. CLI suggestion:- ;rsync on a daily basis, make it a cron job, after the first run backups will on copy changed files. Very fast, minimal space required. ;fsarchiver for your full backups (it'll cope with ext4), requires nfs or samba. ;for convenience use WOL (if available) and run the backups during your downtime. ;not a backup strategy, but useful for recovery purposes - apt-cacher GUI suggestion:- ;kbackintime for daily backups - for network support, I found fish unreliable, the alternative is sshfs and autofs. ;FOG[*1] - I use dedicated boxen for it, but you could install it onto the backup box, or a USBkey. These are by no means the best, or only solutions. My preference is for the cli solutions, point and click clients prefer KBackInTime. Now that your requirements are known others will be better able to give you useful suggestions.
