Hello all,
This is my setup:
ESXi 6 running one VM (win server 2008)
NFS server running on a Linux PC (for backup) and NFS share mounted on ESXi server.
The objective:
Friday evening - Make one full backup (weekly)
Monday to Thursday evenings - create daily snapshot (incremental backups)
Status:
The full backup is pretty straightforward.
I created a script on ESXi sever to suspend the VM and copy files to NFS share then start the VM again.
So if anything goes horribly wrong I can use the backed up VM files.
As far as snapshots I am having difficulty figuring out how best to manage these.
Note: It is unrealistic to do a full backup every evening due to storage, network, and time constraints.
Snapshot Problem:
Scenaro 1: Snapshots stored on NFS location.
If snapshots are saved to NFS location and the running VM becomes corrupt can these snapshots be associated with my VM backup files?
If I change the .vmx config to use NFS as working directory will then VM is running off snapshots that reside in network location causing performance issues (?)
Also some other files will use this new location (eg. swap file and .vmem) which seems a bad idea performance-wise since they are on the network instead of being accessed locally.
Scenario 2: Leave snapshots in working directory and copy nightly to backup on NFS
Leaving the snapshot files in the same working directory requires that I successfully copy all snapshot related files to the network daily.
If I manage to backup all the necessary files correctly I am still faced with the problem of whether these could be applied to the VM backup files rather than the running VM.
-----------------------------------------------
So, not sure how to manage this. Any suggestions or feedback would be greatly appreciated.
Hope this makes sense.
Regards.
