Some requirements of the Volume Shadow Copy option include:

- Volume Shadow Copy is only available on Windows platforms released after Windows 2000 (e.g. XP / 2003 / Vista / 2008 / 7 / SBS 2011).
- The user using the backup application must have administrative privileges to access the Volume Shadow Copy service on a computer.
- At least one of the partitions on the machine must be in NTFS format.
