ATI 2020 Differential Files Deleted
I’m using the Windows version of ATI 2020, and ATI is at version 22.214.171.12410. I have differential full disk backups set to do a full backup then 6 differentials before doing the next full backup. Automatic cleanup is set to keep 4 version chains. I backup to a Synology NAS using WiFi. Last night during a full backup my PC's wireless adapter reset itself about 2 hours and 20 minutes into the backup causing the backup to fail, and I was unaware of the failure until this morning.
This morning Excel wasn’t responding and other things weren’t working, so I rebooted. After the reboot ATI started the full backup again, and this time completed fine. When I checked the backup folder, I noticed all the .tibx files, 13 of them, were gone except the one created this morning and the 12K tibx file. I looked at the log and found messages for all of the deletes for the tibx files, but no error messages that would cause the tibx file deletions.
Because this is the first time I’ve used the differential backup method maybe there is an error in the options or maybe the error from the previous night triggered the deletions. When I did forum searches I didn’t find anything similar to this problem. Does anyone have an idea why the deletions occurred? I’ve attached the logs from last night and today in case they are of any help. Thanks for any help you can provide.
