Stuart, how are you doing your backups? Specifically:
- Which edition are you using? On Home Basic, for instance, all backups are
full
- Is your backup running on a scheduled basis? Or are you manually
triggering a new backup every day? If so, how do you create a new backup
(there are a couple ways to do it)?
To answer your questions about VSS: yes, the File Backup does use VSS, but
in a very different way than CompletePC Backup. For File Backup, a snapshot
is created to make sure we have all opened files flushed from memory to the
file system, using VSS and all involved writers. Once this is done, the
backup reads the files from the snapshot and places them on a zip file.
The .zip includes complete files and we don't store block level information.
The backup includes a catalog that contains information on all files,
including timestamps, etc. Before adding files to backu,p we do a comparison
to check which files should be added.
