So I'd need at least 1 TB just for stuff at my house and room to grow hence the interest in 2 TB drives. >> I am thinking about 2x 2TB actually, one on-site and one offsite cloned >> with something like drbd. > > Sounds kind of scary.

Right now my Photos are add only (and my next big project is to digitize a old record collection); never delete and my system backups are Full/incremental keeping between 6 months and a year. Ideally of course all these files main versions actually live elsewhere.
