"Failed to initialize VSS" when I try to do Exchange Server 2010/2013 Information Store backup

 

Exchange Server 2010 Information Store backup and recovery rely on Volume Shadow Copy Service from Windows. Volume Shadow Copy Service Exception would result in Exchange Server backup failure. Reasons of Volume Shadow Copy Service Exception:

1. There is no NTFS volume.

2. The free space in NTFS is too small to create VSS Snapshot.

3. There are too many Snapshots in system.

4. Some other tools (such as NTbackup) is using the VSS Writer and related components of Exchange Server 2010/2013.

5. If you encounter "Add Snapshot failed"

Case 1:Not Enough Disk Space

Solution:Add space for this disk

 

Case 2: VSS conflict of SharePoint

Solution:Open registry [HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesVSSVssAccessControl], then delete other registry key except "NT AuthorityNetworkService"=dword:00000001

 

Case 3:Registry key error of VSS

Solution:Modify following registry key: [HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesVSSVssAccessControl]

"NT AuthorityNetworkService"=dword:00000001

 

6. If you encounter "Start Snapshot Failed"

Solution:

a. Restart "Volume Shadow Copy" service

b. Restart "Microsoft Exchange Information Store"

 

 

Common Question:

 

Q: Why the second backup image is smaller than the first one when I create full backup for the same content of Exchange Server 2010/2013 Information store?

 

A: With VSS backup method, EaseUS Todo Backup will clean the application log after a full backup of Exchange Server 2010/2013 Information Store.

 However, if the disparity is too large, please send your problem to our support team.
