The script makes snapshot of a VM, copies the "old" vmdk and other files
|
|
|
|
|
to a backup location, then deletes the snapshot.<br>

|

The space use of this approach where every version takes up lot of space
|
|
|
|
|
can be an issue, maybe solved by backup datastore having deduplication,
|
|
|
|
|
but thats maybe for the future.

This approach, where backup in time is full backup takes up a lot of space.
|
|
|
|
|
Some form of deduplication might be a solution.
|
|
|
|
|
|
|
|
|
|
VMs that have any existing snapshot wont get backed up.
|
|
|
|
|
|
|
|
|
|
Files that are backed up:
|
|
|
|
|
|
|
|
|
|
* vmdk - virtual disk file, every virtual disk has a separate file.
|
|
|
|
|
In webgui datastore browser only one vmdk file is seen per disk,
|
|
|
|
|
but on filesystem theres `blabla.vmdk` and `blablka-flat.vmdk`.
|
|
|
|
|
The `flat` one is where the data actually are, the other one is a descriptor
|
|
|
|
|
file.
|
|
|
|
|
* nvram - bios settings of a VM
|
|
|
|
|
* vmx - virtual machine settings, can be edited

### Backup storage locations
|

|
