Hi guys,
For context - I set this ESXi whitebox up some time ago and it was always a test bed; until it wasn't. It now stores a whole bunch of non-critical content (backups, audio, ISO images). Recently my brother somehow installed CryptoWall which nuked about 800Gb of files and we were only able to recover from file level back ups. I'm now home for Christmas and would like to do some maintenance, and implement better backups.
Scenario:
ESXi Whitebox
5x 1TB Harddrives in ZFS Raidz1 (I believe; one failure is the limit)
1x 250GB hard drive for Windows, Open Indiana and PFSense
2x 500GB hard drives for workstation backups (via Server 2012 Essentials)
1x 3TB hard drive for file level backups of the ZFS pool
I have spare...
3x 250GB hard drives
The current 3TB drive simply copies files over, and if they are new or updated, overwrites the existing one. It is a direct mirror of the data.
Problem - the server backed up the 800GB of encrypted files. and nuked the 800gb of good files.
Solution - ?? I'm going to install one of the spare 250GB drives to take a back up of the 250GB Windows, Open Indiana and PFSense drive; I'm not sure how to back this up though. Copy the VMDK? For Windows, use the built in Windows-server backup?
I also seem to be missing shadowfiles when I tried to recover some data. Is there any considerations that need to be made before enabling this? Is there any point?
I understand ZFS has several mechanisms built in as well, so do I enable these and re-configure the pools? I'm thinking snapshots, but have no real understanding of how this works in terms of additional disk space taken up.
Lastly the 3TB drive...it currently mirrors, what is the best way to maximize the use of space? There is around 3TB used on the server, but i'd say 60% is non critical; so I'd rather have GOOD backups of some versus bad backups of all.
Any insight/reading material would be much appreciated. I would go and research all of this individually but the breadth of the problem has led me to the [H].
Thanks,
dL.
