xenserver problem VM disappeared

Looks like this is what he's using? https://github.com/NAUbackup/VmBackup

DO NOT RUN THIS SCRIPT UNLESS YOU ARE COMFORTABLE WITH THESE ACTIONS.

    For vm-export: (a) xe vm-snapshot, (b) xe template-param-set, (c) xe vm-export, (d) xe vm-uninstall on the vm-snapshot.
    For vdi-export: (a) xe vdi-snapshot, (b) xe vdi-param-set, (c) xe vdi-export, (d) xe vdi-destroy on the vdi-snapshot.

No idea what this actually means, but I'm guessing the backup script deleted your base disk (the snapshot?) for the recovered VM?

On a side note, why are you using a backup script when you can use XOCE (Xen Orchestra Community Edition).

Can't +1 this enough, it truly is great.

DustinB3403

@bnrstnr NAUBackup, yeah I used that and immediately got rid of it when I found XO.

It's a solid script but dangerous if you screw up.

DustinB3403

IIRC it does delete the original VM once the restore is completed.

I used it for about a month and it was why I was looking for alternatives and found XO so many years ago now.

Thank you all for your help but sadly i lost my VM, what is worst i dont Know why or how.

Sorry to be the bearer of bad news, hopefully you'll find that XO is a much better approach to managing XenServer.

When it comes to MSSQL, it would've been best to use its own builtin backup instead.

That is true, but it only backups the database.

Backing up the VM you need something that is SQL aware. Which bring up the question, is XO SQL aware. . .

Hrm. . . that is a question worth asking.

Any database, really.

I don't think so. I almost never try to use an image based backup for data.

Yeah I'm not saying it's the best approach, just curious if XO is database aware to pause any activity at backup time. IIRC I don't believe it is.

dariosplit

@black3dynamite That is true, but I use multiple types of backups. Everyone has the advantages and disadvantages. The problem is always time data continuity.

DustinB3403

@scottalanmiller and @dariosplit XO does support the functional (with the use of XS Tools on your VM).
