The idea is to have often-run, incremental backups of my work while I'm out and about and a full system backup run every night. It tests for the backup server locally, and if it can't find it it defaults to the smaller backup and goes for the remote address. I need to write a cleanup routine to keep the size of the incremental backups down, but I like this solution so far. I did a full restore with it today as a test and it worked great.
What do you guys do for your backup scripts? What would you improve on this one?
