Snapshots of a file server.

Hello,

I need to backup up my file server just in case of a power outage. I wanted to do a snapshot in vcenter of the file server virtual machine and wanted to know would the snapshot cover everything in the snapshot in case of a failure? Would the snapshot backup all the files as well.

No. A snapshot of your server is not going to help you, in the event of VM failure and restore.... Making changes to a VM, maybe e.g. Windows Update gone wrong, but I still prefer the Backup before you make any changes, and restore VM, if the VM results in getting broken.

SNAPSHOTS ARE NOT BACKUPS!

Hello,

A snapshot, is not a good option to take it as a backup, because if you take the snapshot of the vm, the size of the snapshot is increasing daily until the datastore is left without space.

You can export your vm to an ova or ovf template and then you can import it into your vcenter in case of a server failure.

You can also clone the vm and convert it into a template, and you have a template in your vcenter of that file server.

Snapshots are used for very short term solution to allow you a reverse path while "testing" only. This time period is not to exceed 2 weeks as a general rule on the outside.

I would recommend using VEEAM or another type of Image level backup applications. Please do not attempt to use snapshots in place of backups. You will do yourself ALOT more harm than good.

For limited use, VEEAM comes In a free version you can use to trial the software.
