very good .. you're just as paranoid as me .. i keep anywhere from 3-6
copies of the same "important" files
- i see you haven't been hit with a power surge that took out everything
connected to the power supply ( disks, motherboard, mem .. etc )
- once is all it takes :-) to put "important" backup elsewhere
than on the same pc
- i'm gonna assume that your nightly incrementals is NOT just for
tonight, but starts from when your last full backup was done
- lets say you did a full backup each sunday ...
- if mondays backup failed, than tue/wed backups are worthless
since mondays changes was not saved anywhere due to any number
of reasons why backups fails ( usually bad nic cable, or our
of disk space or gazillion reasons )
- incrementals should always span across full backups
- weekly backups can span 8 days ..
- monthly backups can span 32 or 62 days ..
.. etc ..
- and new backups should not overwrite previous backups :-)
