storage pool or server backup RRS feed

  • Question

  • When adding a new drive to WHS you have an option to add the drive to the storage pool or to server backup disks.  When and why would you do one or the other?

  • I guess the best way to explain it is that there are really two different kinds of backups here. There are the "backups" achieved through the duplication option for the share. In this case of backup all copies are consuming storage from the storage pool. In the other case of backup it is a point in time snapshot that is copied to another drive, so if you are also using duplication it would be a third, but static point in time copy.

    Yes, I would use a slower USB external drive for the backups. Speed isn't important for the backup pool, but of course you would like them to be reliable even though you hope to never use them.

    I have two external Maxtor Firewire drives that I use for backup purposes, but I also duplicate pretty much every share on the server and therefore hope that I would never have to use them but if things get really bad I have a third option.

    I would recommend keeping your fastest, likely internal, drives for the storage pool and then the externals for the backup pool.

  • You would add a drive to the storage pool if you intended it be used as an active file storage location. You would add a drive to the server backup disks to be used for backing up your selected shares on the server. The drives added to your storage pool go into your servers total available capacity, whereas the drives added for server backup disks are used only when backing up the data stored on the server.

  • So if you had, for example, a slower external USB drive you might choose to have it as a server backup disk, rather than part of the active pool?  Would that then off-load some of the backups to the external drive, giving more space to the active drives?  Or could that be a mistake - relying too much on that external drive for backups?
