Files mysteriously disappearing after running AVG online backup in Cloud Backup Service Posted November 7, 2015 I'm not sure what's triggering the deletes, but it usually happens sometime after the restore. I have Windows Backup scheduled to do a full backup of bare metal, system state, system reserved partition, and the C:\ and D:\ drives. These are backed up to the G:\ drive which is an iSCSI target on the NAS so that it appears as a local drive on the server as opposed to a UNC path of \\server\share. This is so I can get point in time backups locally instead of overwriting previous backups. I also have the Volume Shadow Service (VSS) set as "VSS Copy Backup", which was recommended by Windows Backup since I'm using multiple backup tools on the same server. This is set to run at 2:00 AM daily and generally takes a couple hours to run.AVG in turn is set to run at 6:00 PM daily, I have it set to back up only the D:\ drive since that's where the data resides.Usually when I do a test restore from either the NAS or AVG, I restore it to a different location, rename the original folder, then copy the restored folder to its original location. That said, I have also tried restoring it directly to its original location, but I get the same result. At some random time after I complete the restore, multiple GB of data is missing from the D:\ drive.It might be at midnight, or at 4:00 AM, or pretty much any other time. The only common denominators are that it happens after a file/folder restore has occurred, the files are always removed from the same volume, and both Windows Backup and AVG Online Backup are enabled and set to run on the same server. I have since temporarily disabled AVG backup from running so that I can run a few test restores to see what happens.I should point out too that this is Windows Server 2008 R2 Standard.
