Some background first maybe...
I'm running a small server at home for mainly media and entertaing purposes. The system runs off a microdrive of 4Gb but the data on the drive is rarely over 1Gb. I keep the rest on a separate drive.
I have run this set up successfully for 6-8 months now but I can't get over the fact that using a microdrive still feels a bit shaky. I'd hate to do the install all over again in case of a crash so therefore I've been thinking about setting up a cronjob that backs up the entire disk maybe every two days or so.
I could probably use a raid1 set up but it feels abit overkill so I've been looking at using rsync for this.
My idea is to use something as simple as:
rsync -u -a --delete --exclude "sdb1" / sdb1/
Would this be a good idea?
If the drive should crash, would I be able to just buy a new one, set up the partitions and rsync it back and have a working system? Of course I'll have to activate a swap partition and install a boot loader... but is this a good idea or should I just toss it in the bin and work something else out?
