I can understand that. That's why I use a rotation and retention system
as well as two NASes syncing to one-another with the backups being
performed from the second NAS. I treat them like I used to treat tape.
The onsites contain nightly incrementals as well as weekly full dumps.
These drives are rotated every week. Every month a copy of the latest
full dump is copied to another set of drives which are sent to offsite
storage. I keep two copies offsite. To implement this, I need a
minimum of nine USB drives. I actually have 10 so I can have an extra
one onsite as a hardware replacement-spare.
