Incomplete backup?

Thread needs solution

Ok, so new to True Image, just doing a trial as Time Machine on my Macs is playing up.

I have run a complete backup on two Macs to a Synology NAS with mirrored disks and the backups are showing as completed. However, when I try to test recovering a file, the app allows me to choose the file to recover and then when I say go, it says the file doesn't exist. The logs show the connection successful to the NAS, but the next message is that the specified file does not exist.

Which made me question the backup integrity, obviously.

I then look at the first full backup, which shows a backup of c250gb, but data to recover is 308gb.

Does this mean that it's only backed up 250gb, if so, any ideas why? Logs show successful backup.

I chose backup the full drive, so expected everything - call me old fashioned but that's what I expect of a backup solution, no?

Any help appreciated.

Thanks

The size difference reflects the use of compression when making backup images along with any default exclusions that are applied.  For Windows, files such as pagefile.sys, swapfile.sys & hiberfil.sys are excluded by default which can add up to over 20GB of data - these files are all recreated by Windows on boot so do not need to be included.  There may be similar exclusions on your Mac OS systems?  Compression can normally achieve over 20% size saving if there are a 'normal' mix of files involved - this would be less if the files are already in a highly compressed state, i.e. images, videos, music...
