Hey,
This seems like a pretty huge issue - during a restoration from backups (as it was required), we were checking files that needed to be restored. By the time we had gone to Shadowcopy in order to restore these files,all Shadowcopies had vanished. The only message in Event Viewer was along the lines of:
The Shadowcopies for volumes C: and D: were deleted as there is too much I/O activity on the disk.
From here of course, it meant we were screwed in terms of Onsite backup. I do have a question to ask though:
I can understand that a Shadowcopy may fail once in a while - but what I don't understand, is why would a single Shadowcopy failure end up deletingevery single Shadowcopy ever made? This seems completely ridiculous and is asking to cause a serious inconvenience and data loss on servers. Is there any reason why
(a) The Shadowcopy could not pause or otherwise keep what it has already done
and
(b) The Shadowcopy could not touch previous Shadowcopies, let alone delete every single one of them
Of course I understand from here that On-site backups are not flawless and there is Off-site backups as a solution - but I would really prefer to know why this issue occurs, why it does what it does as a result, and how to best avoid the problem again in future.
