Scope: I have two discs with 4 TB. One is used as home. I wish to run home on a RAID1. But I have no means to do a backup of all data.
very bad idea. your home content is probably not 4Tb (else the disk would be too small), so backup it *first*
a raid, any raid, is no backup at all. Even, make *two* backups if you home content is of any matter for you!
Right. If you have two disks, the correct thing is to use one, and the other as offline backup. Ie, plug the disk, make a backup, remove the disk. If a mirror is wanted, then the correct thing is to have three disks. Two for the raid, another for external offline backup. -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)
