Time. Effort. Costs of tapes (especially if we keep one-to-one - i.e., each EOM is a separate tape, regardless of how much more can fit on one tape). Disk space to restore onto. Other things ...
If a tape goes bad (which we've had happen), then we lose only 1 month data. If we had multiple EOMs on one tape, losing a tape woulfd be BAD. :-) On Fri, Jun 3, 2011 at 5:32 PM, David Lum <david....@nwea.org> wrote: > Why not do a one-time restore of really old backups to your newer backup > medium?
