To store the copied original pages, the snapshot uses one or more sparse files. To the user, a database snapshot appears never to change, because read operations on a database snapshot always access the original data pages, regardless of where they reside. The same process is repeated for every page that is being modified for the first time. The snapshot stores the original page, preserving the data records as they existed when the snapshot was created. Before a page of the source database is modified for the first time, the original page is copied from the source database to the snapshot. Prerequisites for and Limitations on Database Snapshotsĭatabase snapshots operate at the data-page level. Here, read this review about AOMEI Backupper.Database snapshots are unrelated to snapshot backups, snapshot isolation of transactions, or snapshot replication. Very appealing and easy to use interface.System image mounting to explore files.Disk cloning, system backup to image OS, files backup.Supports incremental and differential backups to save imaging space and time.
Can make bootable disks in case Windows is not starting,.The AOMEI Backupper Recovery Tool, I've been using it to create system image for a while now (made a quick test to restore my C: drive and the drive was back and the extra added files were gone as expected) and I'm impressed with it's ease of use and good speed. Now, as for a third party software, one good tool is: System image to restore the contents of your computer if your hardĬheck out this for Windows 7, this and this for Windows 8. Windows and your system settings, programs, and files.
Includes the drives required for Windows to run. Therefore I recommend to accompany this Windows tool with a full disk image tool of your choice.Ī system image is an exact copy of a drive. Because if Windows it self crashes, then it won't be able to restore it self back! Especially in the event of hard drive crash then everything will be lost.
But personally, I wouldn't rely on it that much. If you are using Windows 8 (and Windows 7 as well), they have included this feature as System Image which seems promising.
