XO File Level Restore Question
-
So this is the procedure I did...
- took a full backup
- took a delta backup
- made some changes
- took another delta
The first delta, I can do a file level restore. The second, I cannot, and get this in the logs...
"message": "Command failed: mount --options=loop,ro --source=/tmp/tmp-807MrncKsoRdVxi/vhdi3 --target=/tmp/tmp-807IHywqgWplCug
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error -
@BRRABill The fact that you took the full doesn't matter.
You took a delta, made some changes and took a second delta.
The message you're getting is what needs to be addressed. Which I believe the error means you are missing a critical component to mount the file system.

Alrighty, guess we'll wait for @olivier

But you are saying if you'd never taken a delta before, if would do a full first, right?

It should, but it's still marked as a delta in the system. You'll notice it takes longer then the subsequent delta.

I wonder what would happen if you took a full backup after taking a few deltas.
I guess that is the chain part that is confusing me a bit.

I wouldn't know. I'd imagine it would be just fine. Unless it's keeping a snapshot on XS for some reason... which could break the chain as the delta backup is looking for a specific set of files.

I would hope if you took another full after taking some deltas that either a) it wouldn't affect the old deltas at all, or b) it would cap them, and any new deltas would be based on the new full backup.

I wonder if this is a backup theory question, or specific to each product.

Probably some of both.

I ended up posting on their forum.
It's strange.
I have 4 deltas. The first one works, the others do not.
In have been taking deltas every hour. When the second oldest (which cannot be read) becomes the oldest, t can then be read.
-
@BRRABill Hrm... I'm curious if there is a bug...
-
I upgraded my XO VM today and now the file restore isn't working on many of my VMs.
-
Something interesting is that when I went into the directory that was giving the error, it was empty.
-
@BRRABill for the initial delta, or for every delta?
Likely a new bug...

@Danp said my vhdimount is the wrong version, so going to try that first.
Then I will check the deltas.

@BRRABill What version do you have?

20160108

@BRRABill you're out of date from what I have.

libvhdi-utils/yakkety,now 20160424-1On the XO forum, we've determined I should probably be on 16.10.
Are you on 16.10?
