Hello experts,
I hope some of you can give me an insight, what's happening here with Windows BACKUP on server 2012R2 - is this new behaviour "by design" is is some bug involved. ....or is it me and my lack of expertise.
I have one single Windows Server 2012R2 setup as a DC and File Share for a company with 50 users.
I configured WINDOWS BACKUP to use two destinations:
- first destination is "Volume" type, iSCSI target on NAS server
- the second destionation is also "Volume" type, partition on local RAID1 disk array
The SIZE of those destinations are both 1,5TB, while all backed up items together are below 350 GB, so there's plenty of space on both volumes.
PROBLEM?
Yes, problem is, that Windows Backup uses only 1 of destinations for some time. It counts...1 backup copy available, then 2 copies available and so on...then it suddenly drops count back to only 1 copy available on this destination, and switches to 2nd destination. Totaly unpredictible and unreliable, because:
- if something happens when 16 copies are available, it's OK, I can restore 16 steps back
- but what if something goes wrong when it shows only 1 copy is available?
I have quite a few Windows 2008 Servers running out there with 2 destinations, and they fill up BOTH destinations at the same time, having 30+ backups available on BOTH destinations.
So I am wondering, what's wrong with my server, so it behaves so much differently as old 2008 servers?
