If I see anyone calling replication for backup, I'll...
Rip their head off, toss it in the toilet and flush...
Replication may be a good 'disaster recovery' function, but when a user calls and wants something restored to the state it was in last month, what then?
(In all my years as a BOFH I've never had to do a disaster recovery, but user-requested restores happens almost daily. )
At my office we're required to keep backups for 10 years. Can anyone think of a suitable media for storing TBs of data, except tape?
