Different full backup size - decreased by a half!

Thread needs solution

Hi

I accidently deleted my incremental backup regeme and so set up a new one - Incremental again.

I have just run the first backup and noticed that the resulant file size is around a half that of the previous full backup (1st Jusy) - 253,848,848KB as opposed to 505,799,125KB.  The used space on the HDD (2TB) is 717,007,609,856KB.

I don't recall deleting vast ammounts of data so what has happened to the missing data?

I'm not doing a sector backup.  I'm currently running W7 and need to backup the system disk before I move to W10.  I will also be cloning the HDD before I do the update.

Any help or advice appreciated.

Thanks

Pietro

Pietro,

I would recommend downloading the Log File Viewer app and checking for any messages that are posted in the Service logs for your new full backup and comparing these with the logs from your old backup task to see if there are any obvious differences shown.

The other option here is to mount your new backup image as a new drive letter, i.e. as drive P: then do a comparison of the contents with the source drive.

See webpage: Best Free File Comparison Utility for a review of different utilities that can be used to compare files / folders.

Or see: Directory Compare Portable  or  FreeFileSync  which can compare folders / contents (plus much more).

Thanks for repling Steve.

I was not able to do the 2nd option as the backup was a TIB file - and so not an image.

I was also not able to do the first, as I deleted the TIB and Logs from earlier when I deleted the regeme.  I did try Log File Viewer on some other log files, but it only worked once and then hung every other time I started it.

What I have now done is delete all the regeims that I had, moved all TIBs to a safe location and set up a new incremental regeme.  I notice this time that int he Disks and Partitions box it says 675.2GB, which I think is correct for the first backup in an Incremental series for this drive.

Fingers crossed that this works OK overnight and I can get goung with the clone before I do the upgrade to W10.

Thanks again

Pietro

Pietro, thanks for the update.

All Acronis .TIB files can be either mounted as a drive letter (if it is of Disks / Partitions) or else can be explored for all types of backup .TIB file.

Good luck with the new backups.
