i dont have time to play with tapes.. daily changing it..
- forget one day... and you're hosed
if you're using tapes for weekly offline backups.. no problem
find /etc /home /... -mtime -90 -type f | tar zcvf /dev/tape -T -
( 90 days worth of changes )
i prefer 100GB - 1TB of disks to be backed up to other disks ...
( tapes are too small for "full backups" and definitely too slow )
- i do daily, weekly, monthly incrementals
- i want the backup to be live within a few minutes
of the main server going down for whatever reason
- i assume "yesterdays or last weeks" tape/disk/backups is BAD
and can still receover everything from day before or tonights
backup ...
- i want a "hands off backup"... if i go away for vacation
for a week/month... the systems are still properly backed up
( semi-guaranteed )
- i can lose 2 FULL backups and still recover everything
backup example scripts and why backups fail too
