[backup method] tar or dump for backups?
I have a spare 1 GB disk at work which I could use to backup my /home
partition (which consists of 1 GB amidst a 4.3 GB disk).
(If I decide I can tolerate the 1GB-disk's whining; it's surprising how
annoying the sound of the old disk is compared to my new Seagate
Barracuda.)
I'm accustomed to using tar. I thought I'd learn about incremental tar
archives and:
o erase the disk every Friday evening and make a new tar file
on the disk.
o create an incremental tar file from Monday to Thursday evenings.
Is this wise? Or should I use dump/restore which I know nothing about?
Part of the protection I want is from myself:
If I accidentally delete a file on Monday and it takes me until
Thursday to realise that, I'd like the file to still exist on the backup.
Perhaps incremental tar deletes a newly deleted file from the tar file
to keep in sync with the disk, thus defeating part of my purpose?
I'd appreciate any suggestions!
