wacko37 Posted March 18, 2023 Share Posted March 18, 2023 +1 Still struggling to understand why this is not already a feature? How is everyone dealing with backups of their VM's without this feature? Quote Link to comment

How is everyone dealing with backups of their VM's without this feature? Client / server based backups. If you install a proper backup software inside the VM, it can do valid backups without taking down the VM. I personally use UrBackup, there is a container for it in the app section of Unraid, but you can just as easily use the built in windows backup if you are using microsoft products, or acronis, or any number of proper backup softwares. Doing it this way instead of trying to do a live image snapshot ensures you will have a valid backup instead of a crash consistent one. If you restore a snapshot that was taken of a running VM, you risk the snapshot not containing a valid backup, because there is no way for the VM client to know that it needs to commit changes from RAM to disk. Snapshots of VM's are only a good backup if you are willing to properly shut down the VM before taking the snapshot, or have some other feature in the VM to allow a live snapshot to work 100% of the time. Much easier to not reinvent the wheel and use good backup software in the VM. Quote Link to comment

This feature there is so simple and reliable... you just have to add a backup plan or you can do the snapshot manually with one click!- even when the VM is running. Restoring is super easy too... choose the snapshot you like and hit the restore button. Please! 🥲 Edited March 22, 2023 by enJOyIT 1 Quote Link to comment

Aumoenoav Posted July 13, 2023 Share Posted July 13, 2023 Completely agree! I feel its a very important function that is missing in unraid GUI. The CLI version doesnt work it seems, but a snapshot before a big update is extremely handy! Quote Link to comment
MoldavianRO Posted July 16, 2023 Share Posted July 16, 2023 Yes please, just doing a reinstall when a snapshot could have easily saved me... Quote Link to comment
Vinsens Posted September 11, 2023 Share Posted September 11, 2023 +1 we absolutely need a simple snapshot option in the GUI Quote Link to comment
Kev600 Posted September 23, 2023 Share Posted September 23, 2023 Please please can this be added - I'm just about to splash out on better hardware to use VM's more with my UNRaid set up. Snapshots are one of 'THE' benefits of VM management. 🙏 Quote Link to comment
DrLucasMendes Posted November 24, 2023 Share Posted November 24, 2023 I found this comment in reddit. "You can snapshot VMs as unraid provides them default by navigating to the storage device it exists on, and doing cp --reflink=always vdisk1.img vidks1_snapshot.img" Regarding refllink: "The reflink is typically meant for whole files but a partial file range can be also copied, though there are no ready-made tools for that. cp --reflink=always source target" https://btrfs.readthedocs.io/en/latest/Reflink.html Quote Link to comment
casperse Posted January 10 Share Posted January 10 (edited) +1 YES! and for the APP (I know there is a script/way to do this but native funct. is much better) Edited January 10 by casperse Quote Link to comment
s1l3nce Posted February 18 Share Posted February 18 (edited) I've been using Virtualbox and Proxmox for a while and having snapshots is a must have for virtualisation. Not having it on Unraid is not a deal-breaker but it's a bit frustrating. Edited February 18 by s1l3nce Quote Link to comment
libook Posted February 23 Share Posted February 23 +1 Currently using virt-manager to connect to unraid's backend, creating a snapshot: “Error creating snapshot: Operation not supported: internal snapshots of a VM with pflash based firmware are not supported“ Quote Link to comment
Darkestnoir Posted February 27 Share Posted February 27 +1 I am coming from Proxmox and this feature is really needed! Quote Link to comment
