By using NTFS volume mountpoint support, SnapManager can manage databases that are stored on mounted volumes, in addition to those stored on standard Windows volumes. With SnapManager, your configuration is not limited to the 26 letters of the alphabet to name drives in Windows.
SnapManager needs one LUN and one available drive letter to perform backup, verification, or restore operations.
If you need to restore many databases individually, you likely need more than the total limit of 26 drives.
Windows supports up to 26 drives, and you can allocate a maximum of 25 drive letters with releases of SnapManager prior to 5.0. You can avoid running out of available drive letters by determining which databases must be restored individually and which can be combined on a LUN with one or two other databases and all restored together. With this approach, you must still reserve at least one free drive letter for SnapManager.
