Rotating backup media is becoming a thing of the past. A lot of organizations are moving to cloud backup or backing up to some NSA/SAN or other connected device. In an environment where changing disks/tapes is hard like in a data centre then the single backup device is attractive.
I do work for a backup provider and they have a large number of companies who in essence have a single point of failure for their backups.
For better or for worse people are moving their backups offsite but into a single location.
Well at the very least you should use multiple remote instances that you can mount and backup to. If you have a single remote storage pool for backups, then you do in fact have zero backups while doing a new backup. There is no reason you could not have multiple separate storage pools that you only ever mount one of at a time to avoid anything stupid wiping out old backups while doing a new one. But I supose this cloud stuff really is making people stupid. They can't imagine anything could go wrong with the cloud.
True enough but testing your recovery processes is something that is seldom done. Taking systems offline to do a full recovery is just too big a pain.
Yep, but it means you very well might not have a backup. If it really mattered you would have spare hardware for testing and disaster recovery already, in which case the test would not be that hard.
You also have to do the recovery testing on a regular basis.
For sure. Even less likely to be done than testing it once. -- Len Sorensen
