I do not want to be stuck with a bad full back up in an emergency. Many enterprise backup solutions support disk now. When I had Commvault, I did a full and all my incrementals to a big fat RAID array (simple Dell PowerVault) hanging off my media server (the Commvault piece that drove the tape library too). Once a week I would do what Commvault calls a synthetic full backup to tape for my weeklies. I kept four weeks of incrementals on disk. That gave me fast restores from the incremental backups since they were located on disk, but gave me complete sets of full backups on tape - best of both worlds. At the end of the fourth week, would have the backup on the disk recycle and start over. Dunno if other software can do that too - was a snap with Commvault. Synthetic full backups are backups that are created entirely inside of the backup system - Commvault would basically do a restore internally to the tape drive to create the full backups. You never touched the application servers to do these as they are done entirely inside the backup system, hence the term Synthetic. A nice way to do it since it doesn't put additional load on your production systems. You can also do backups (synthetic or otherwise) across the WAN for DR - we would just do perpetual incremental backups to remote sites, then at the remote site do synthetic fulls to get viable self-contained backups. If you have enough disk/tape you only have to reset your incremental backups quarterly or every six months - saves on WAN bandwidth.

Back Up Best Practices
What is the latest recommendation on back up processes? We have been small enough to do full back ups daily for some time, but now face time issues with that and need to move to a tiered option. Is F-I-I-I-I reasonable anymore or is it too risky?

RE: Back Up Best Practices
You should always verify and test your backups.

RE: Back Up Best Practices
For clients who don't have time, you should look at d2d2t which is disk to disk to tape You get disk to disk backups after hours, then you can let the tape run throughout the day without affecting files, bandwidth etc. I guess it depends on amount of data and speed of backup system. The LTO loader my client has does about 1gb/min.

Re: Back Up Best Practices
We had BE 11D and an LTO3 autoloader. We do do some D2D prior to tape for our VM image back ups. We should look at possibly doing more of that.

RE: Back Up Best Practices
You could also look at san snapshots too , if you have an iscsi appliance or similar. You can get full snapshots in just a few minutes of terabytes, but then you still have to get that to tape. The way we used to do it before d2d2t was to put 2nd nics, and switch between the backup server and servers. On their own subnet and nic we could get full throughput and backup without affecting a lot of performance within the network. The i/o of the disks could usually handle it, and obviously sql/exchange aware backups can run in real time.

If your iSCSI device and your backup software supports VSS transportable snapshots, you can get them off the SAN at any time without having to burden your production server.
