I have a system with two disks, each with some space, so I'm contemplating backing up the contents of each onto the other.
So you are currently using less than half of your total disk space?
Yes, that's right.
I'd prefer a system that just mirrored the files, rather than consolidate them into an archive. Then I'll just update the mirrors each day.
Unison is nice. It allows you to be selective about what you will copy, and it can be run under cron so it will get done regularly. Its usually used between two different machines, but I don't see why it wouldn't work between two drives.
I used to use Unison to sync two machines. I found it had problems with files that change between its scan and copy phases (such as mail folders).
Any ideas on what the best way to do this is (cp -a, rsync ??) or suggestions as to a better alternative?
Thanks, Dave
If you really can fit totally on one disk, you could repartition and mirror the drives with software raid. Its the easiest to keep in sync, and utterly reliable. But the re-partition and re-installation is probably a huge pain.
That's a good idea. But the disks are significantly different sizes and as you say, re-partitioning etc is more pain than I'm looking for.
