Snapshot Backup - FAQ How can I verify that Snapshot did what it claimed - backup all my data The easiest and fastest way: Backup a drive. Map the drive as virtual drive. Use WINDIFF or similar file compare tools to compare the two drives; they should be identical. You will see differences, because WINDIFF will not be able to open the PAGEFILE or registry files on the original drive; but that's not SNAPSHOT's fault. For these files you have to trust us (of course we tested this, using slightly more complicated setup's) Do I have to shut down all Windows programs (highly recommended) No. It's probably a good idea to save your open files before starting Snapshot Backup. Otherwise you would eventually get outdated data on your disk. After Snapshot has started you may continue to work normally, the image will reflect the data at start time. May I install a new VIRUS, while Snapshot is running? Yes. It won't make you happy, but Snapshot won't care. The created image will not contain any sign of a virus, ready to be restored. May I FORMAT/FDISK the disk that is currently being Snapshot'ed? No. It is not possible to run programs that access the disk directly while Snapshot is running. What File systems does Snapshot support? SnapShot relies mostly on the operating system to support a drive. All file systems known to Windows(FAT16, FAT32, NTFS) are supported; additionally some LINUX file systems (EXT2,EXT3,Reiser) are 'manually' supported. Other file system are stored completely, ignoring any free space information. Does Snapshot support enhanced NTFS features like encryption, security, hard and symbolic links, mount points, multiple data streams, extended attributes,quota,... Yes. Snapshot is sector-oriented. Snapshot will backup all sectors relevant for the file system, and restore them exactly the same way. Snapshot never interprets these data on its own, the interpretation of these data is up to the file system. Snapshot only provides the necessary data. The same is true for the Image Viewer. --------------------------------------------------------------------------------
