Searched around and have seen others with this issue but no real solutions.
I have a 14TB Deduplicated volume that loses its vss about once a month. I just lost this lasts night and have seen some interesting stuff.
First the error
The shadow copies of volume E: were deleted because the shadow copy storage could not grow in time.
Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.
PS C:\Windows\system32> vssadmin list shadowstorage /for=e:
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool(C) Copyright 2001-2012 Microsoft Corp.Shadow Copy Storage association
For volume: (E:)\\?\Volume{9b6bb5ae-8d5e-4f13-94ac-8655fc90e4f2}\
Shadow Copy Storage volume: (E:)\\?\Volume{9b6bb5ae-8d5e-4f13-94ac-8655fc90e4f2}\
Used Shadow Copy Storage space: 507 MB (0%)
Allocated Shadow Copy Storage space: 3.14 GB (0%)
Maximum Shadow Copy Storage space: 1.40 TB (9%)
If i look at previous versions i only show the snapshot from this morning at 7:00 AM
However if i type vssadmin list shadows. it shows 30+ Contents of shadow copy set ID.
I am starting to run low on space but i still have over 20% free and over 3.1TB of space.
Any ideas here?
