Activity/Backedup size differs to size of backup files?

Thread needs solution

Hi all,

Using ATI2018 on a Win10 Pro x64, backup media is a synology NAS, doing only full backups manually into different date folders.

What jumped into my eyes now is that under activity / I see sucessfully backup up 85.4 GB (data to recover 97.6 GB).

When I check the file size from that day in my backup folder on NAS disk they are only 44.5 GB ?

Is this normal ? (compression?)

TIA for your feedback.

Daniel, welcome to these User Forums.

The answer to your question is covered in the ATI 2018 User Guide: Backup activity and statistics

where it says:

Backup operation details, including:

  • Backed up—Size of backed-up data, with compression.
  • Speed—Backup operation speed.
  • Time spent—Time spent for the backup operation.
  • Data to recover—Initial size of data, without compression.
