Backup taking up large amounts of diskspace RRS feed

  • Question

  • I have been backing up daily.  The original full backup was 37GB.  After 17 days of daily backups, the folder containing the backups grew to 138GB.  The computer being backed up gained approximately 100MB of files during those 17 days.  Why are the backup files 100GB larger in size if the computer being backed up only gained 100MB?

  • It sounds like OneCare thinks that many more files than the 100 MB you note are changed or new, hence the very large amount of space used. Obviously, that isn't desirable, though. You may want to contact support or file a bug on Connect about this.

  • Are you editing any of your video files? How big is your email file?

     

    Onecare backs up whole file again if the time stamp changed, or at least a single line is added.

     

    Just start and incremental backup and see how much it is taking. You can check which files are in by running a scan from Backup Configuration page. (Change Settings --> Backup Tab --> Configure Backup --> Change File Type --> See which file type and how much amount is going in this incremental backup)

     

    This gives some understanding of what is going in as part of daily backup.

     

    If you want a quick fix, make sure yuo don't have any missed file (you can check in restore wizard) and format the hard disk and make a new backup which will be again 40GB, I hope next incremental backup will be more meaningful.
