Periodically we get following error:
Date: 18.03.2015 21:08:39
Type: Error
Priority: High
Beschreibung: Fehler EC8F17B7: Wiederherstellungspunkte können nicht erstellt werden für Auftrag: Laufwerk Z:.
Fehler E4F3000E: Snapshot failure while using Volume Shadow Copy Service. Please check application event log for VSS errors. Error code: VSS_E_FLUSH_WRITES_TIMEOUT (-2.147.212.525).
Details: 0xE4F3000E
This is what we have already done:
- In Trend Micro Antivirus we have excluded the Symantec folder
- attached new external USB Drives
- removed old Devices from the device list
- created new backup jobs
- split the jobs, one for each drive
- changed backup start time
- turned encryption on/off
- weekly defrag of drives (max. 3-4% fragmentation)
- manually creating a shadowcopy works OK
- ran C:\Program Files\Symantec\Symantec System Recovery\Fixinstall.bat
Additional information:
> vssadmin list providers: "Microsoft Software Shadow Copy provider 1.0" (should be standard for 2013 version)
- If we run "vssadmin list writers", many appear in a " bad state" and we only can fix this with a server restart.
- After the server restart, every writer is fine and the backup works for a few days (max 1 week)
- However, if you log onto the server and manually start the backup, it works! Only the scheduled job aborts after 10 minutes.
Any ideas or tips on what we can do to try and resolve this problem? Many thanks.
