Restore Sets

To restore a folder or mailbox, you must select the object you want to restore in all of the sessions that, when combined, completely restore the folder or mailbox. These sessions are called your restore set.

• If you backed up your folder or mailbox using both full and incremental backups, your restore set includes your full session and at least one, but up to as many incremental sessions as you want to include. For example, in the following backup scenario, your restore set can be full and incremental 1, full and incremental 1 and 2, full and incremental 1, 2, and 3, or full and incremental 1, 2, 3, and 4:

For example, in the following backup scenario, your restore set can be full and differential 1, full and differential 2, full and differential 3, or full and differential 4:
