How to Backup VMware VMs?
If you’ve no salery cap left, like me. You want to use an Open-Source tool.
I’d love to use GhettoVCB: On Github
I’ll list some usecaeses below.
My environment contains:
- ESX 6.5
Backup single VM:
- Backup VMs including a list:
$ ./ghettoVCB.sh -m "<VM name>" -g /opt/ghettovcb/conf/backup.conf
- Backup VMs with an excluding list:
- vm2 and vm4 will be backed up
- vm1, vm3 and vm5 will be excluded from the Backup
$ cat vm_exclusion_listvm1
vm5$ ./ghettoVCB.sh -a -e vm_exclusion_list
- Backup all VMs on ESX:
$ ./ghettoVCB.sh -a -g /opt/ghettovcb/conf/backup.conf
If your backup is bigger than your used diskspace than you’ve junk left on your harddrive (which was alread deleted).
$ df -hd 1
In this case, you’ve to override it with zeroes, to make your thin-provisioned disk small again.
To do so you just have to type the following command:
Single partition systems:
$ df -h ; time dd if=/dev/zero of=/EMPTY ; df -h ; time rm -f /EMPTY
Download sdelete (windows utility)
$ sdelete -z c:
Multi partition systems:
If you have multiple disks (var for example), you should use something like this:
$ dd if=/dev/zero of=/var/EMPTY ; df -h ; time rm -f /var/EMPTY
If you now backup again, you’ll see that only mostly your used diskspace will remain in your backup.
After overriding the free space with zero’s:
$ df -hd 1
