Large file server backup - Best practice

Post by perjonsson1960 »

Folks,

What is the best practice for backing up a large physical file server cluster, using B&R and the Windows Agent? The amount of data is currently around 15 TB.

Which backup method is commonly used for large file servers? Should we use "forward incremental" with synthetic fulls, or "forever forward incremental"? All our backup repositories have dedup enabled, and we have one scale-out repo for the backups, and another scale-out repo for the backup copies, at another physical location. Currently all our backup jobs use a 14 day retention period, and the backup copy jobs use a 7 day retention period, but some of them use a GFS policy with weekly, monthly and yearly full backups on disk. And beyond that, we are backing up everything to tape once a month.

This file server cluster is by far the largest "device" to be backed up by B&R in our organization.

Hello Per,

Moved this post to the agent subforum.

Stay with entire computer backup mode (or volume level backup mode) and make sure that you have CBT driver installed.

If you have enough space to keep multiple full backups I'd say go with forward incremental with periodic fulls. If you have enough space to keep only one full backup - forever forward incremental is the best.
All our backup repositories have dedup enabled,
Make sure you have backup job encryption disabled otherwise it will impact the deduplication ratio.
