We have this feature in our new panel which is currently limited to a few clients for beta testing, here's a few screenshots: http://imgur.com/a/afjYR
Vultr has this feature too.
Most don't. Solusvm has to provide it and I've never seen anything like that there.
Even the solusvm backup option is said to be buggy.
I've been trying to figure that part out , just out of curiosity its just like making a copy of the containter's disk right ?
Some providers may be using ProxMox which really has a good snapshot feature.
I've tested it and it works flawlessly every time.
Dediserve
2 ways to get it done, each has it's merits and demerits though.
Which means still Digital Ocean is best for this task?
I think Iwstack XEN instance have entive VM Snapshot option it use cloudstack.
DO is not the best... you will have snapshots on running vm only on their auto backup system
Openvz web panel provider can give you snapshots ability with Suspended for several minutes VPS or with stopped, if you find one which offer ploop (but i doubt there is low end ones cause there certain requirements to use it safe and usually use more space than simfs) will give you running snapshots)
or Proxmox provider can give you better options than DO
Can you elaborate a bit more? I can take snapshots without having any "auto backup" feature enabled...
You can take snapshot on DO but VM should be stopped during snapshot taking place... If you enable auto backup (cost 20% of price of vps plan) they do running vm backups every several days...
That was the situation several months ago when i used them ...
With OpenVZ web panel on ploop you can snapshot backup running one, on proxmox with qcow2 partition also can snapshot a running one (see screenshots in my previous post) ... which is the best option for bigger than several GB VMs that why I mean DO is not the best for snapshot
Proxmox has a snapshot function. A few of the more common virtualization panels also have some backup options that may cover what you want.
www.rijx.com also has a cool snapshot feature!
Bandwagonhost has snapshot function.
We offer this on our impact vps brand
Vultr has snapshots and I think iwStack does
Yes it's also possible to snapshot disks of KVM instances although if the VM is running there's always the risk of an inconsistent FS if you simply snapshot the disk.
Snapshots should not be a replacement for a backup. But they are great for making clones of VMs
Inconsistent FS, no, if everything runs as it should, but inconsistent DB, might be.
With xen you can snapshot the running VM including memory, will continue from the snapshot moment onwards in case of restore. KVM does not support this feature AND you must never save more than one disk at a time, the snapshot will fail.
Snapshots can be manual or scheduled, witht he caveat that you must account for the time needed to backup one disk at a time for KVM. This will create issues if you have a need for the 2 to be in sync. Best way to do it is to have only one disk, but, if you must have more, then group the data which needs to be consistent on the same disk.
You can then convert the snapshots to templates, but must be sure you do not have any MAC or IP hardcoded, otherwise the resulting VM will not have net access until you solve these problems.
The good people at redhat are working on KVM live migrations ( http://developerblog.redhat.com/2015/03/24/live-migrating-qemu-kvm-virtual-machines/ a cool read btw) so I assume they can do live snapshots soon.
Maybe that's the problem. It would be nice to see more hosts making a commitment with their own panels, that they understand and can adapt to their needs and the needs of their clients.
Relying solely on a third party vendor for your control panel and feature set heavily limits your ability to innovate and set yourself ahead of the competition.
That's correct, in order to run a snapshot at DigitalOcean you must power down the VM, run the snapshot and wait for it to complete, power up again. If you are looking for a host with the ability to take live snapshots, Vultr comes to mind.
Our platform lets you schedule automated snapshots (daily, weekly, etc) as well as on demand.
