Backup Fail: Trying to add data in unsupported state

olivierlambert

It might be related to BackBlaze being overloaded at some point. Our advice:

reduce backup concurrency
reduce block concurrency during upload (writeblockConcurrency) and merge (mergeBlockConcurrency) in the config.toml

Of note from ours is we use Wasabi S3-compatible as the remote in one case and a Synology NAS as our local remote in the other. Both of those remotes fail with the unsupported state error when the backups are encrypted.

In the same encrypted job I have the following machines which have a backup size and duration of:

VM1 - 31.55GB - 47 mins
VM2 - 14.51GB - 22 mins
VM3 - 30.28GB - 48 mins
VM4 - 45.33GB - 24 mins
VM5 - FAIL - 1hr 27 min
VM6 - 2.14GB - 4 mins
VM7 - FAIL - 1hr 28 min
VM8 - 35.95GB - 1hr 5 min

The two machines erroring have thin provisioned disks whose size are
VM5 -- 128GB and 100GB which are 10.94GB and 86MB on disk
VM7 -- 123GB and 128GB which are 11.09GB and 10.3MB on disk

At first I thought it was size related or perhaps duration. But what's causing that extra duration for machines of these sizes? Something about activity on the Windows VMs?

Or perhaps that it was related to having multiple disks on Windows machines?

It might be a different problem (zstd compression failing on the host) vs a problem with the S3 provider. That's why I'd like to sort the two things.

yesterday I reduced writeblockConcurrency to 12 and started the backup.
Same error. I will try some other values.

Here is the error message from the orchestra.log file:

I have now tested several times with several different values. But getting the same result with every attempt. The error occurs after about 3 hours.

And I don't think it's a Backblaze bug.

For testing purposes, I installed a local Minio server and added it as an encrypted remote in Xen Orchestra.
The same error occurs. The error occurs every time after about 12 - 13 minutes.

In my test job(full mirroring with selected vms) are 2 VM Backups. A small one (xo with about 7GB) that is mirrored correctly on the first try on both remotes (Minio and Backblaze).
The error occurs after about the same amount of time every time when mirroring the large VM (tried various large VM backups...).

Then I created another minio remote(another bucket) without encryption and run the same backup mirror job to the unencrypted remote.
And this time, it went through without any errors...

So it must be a bug related to S3 remotes, large VMs, full mirroring and encryption!

I'd love to see if you have the same error with AWS S3, because that would tremendously help to debug.

@olivierlambert
sorry no AWS to test

I am seeing this problem on a encrypted NFS remote (server runs unRAID), too. Only one VM out of 6 VMs that get full backup. Always the same VM shows this error. The same schedule for these VMs did not produce this error on an unencrypted NFS remote on the same server. Also, using delta backup instead full backup on the same encrypted remote does not produce this error.

"stack": "Error: Trying to add data in unsupported state\n    at Cipheriv.update (node:internal/crypto/cipher:181:29)\n    at /etc/xen-orchestra/@xen-orchestra/fs/dist/_encryptor.js:52:22\n    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)\n    at async pumpToNode (node:internal/streams/pipeline:135:22)"

Are there any news regarding this issue?

daniel.grimm

Nothing new to this.

But now it sounds like an encryption problem. Seems like it has nothing to do with cloud storage.

djingo

@daniel-grimm definitely not related to cloud in my case!
