Failed to backup [Users\Reception\Pictures\2016-07-27\Foodservice 270716 003.jpg]
Error: Timed out to wait until the size of mount cache will be less than threshold Agent failed to process method {FileBackup.SyncDirs}.
It keeps retrying but then failing with the same error.
Machine:
Windows 7 Pro
Veeam Endpoint Backup 1.5.0.306
1. Open Registry Editor.
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Endpoint Backup.
3. Create the following DWORD: EndPointBlockSize and set the value to 256 (decimal).
4. Close Regedit and restart the Veeam Endpoint Backup service (or reboot the machine).
To apply changes, Veeam needs to start a new backup chain. PLease either select another backup location (so Veeam will create a new full backup), or use the registry key called "RecreateDatabase" and set its value to 1. It will purge all data from Veeam Endpoint database (it will look like a fresh install). Veeam service restart is needed.
The only downside is this will force me to create new backups. Bit annoying as sites are remote, but will have to create a new seed on a drive and have it shipped
