Backup copy job takes too long to generate blocks, causing source backup job to fail

Post by Yukinobu »

Hi,

Our cudtomer is using QNAP object storage as the target for a backup copy job with immutability enabled.

I don't know if this is a QNAP issue, but the backup copy job is completed every 10 days when blocks are generated, and takes more than 24 hours.
object-storage-as-backup-target-f52/qna ... 85139.html

As a result, even the backup job fails with the following error.

Code: Select all

Item [<vib file name>] is locked by running session Immutable Backup Job - <Backup copy job name> [Backup Copy]
When I checked the log, the incremental transfer was completed in
several tens of minutes, and it seems that the extension of the immutability period is taking time.

Code: Select all

[21.06.2025 02:00:05.997]    <46>    Info (3)    Created CCloudBackupEmptyLocker
When I checked this with Veeam support (Case # 07740686), Veeam support was told that the backup copy job keeps the source backup locked during the immutability period extension process in order to analyze the chain structure of the source backup.

Is this true?

After analyzing the chain structure of the source backup and unlocking the source backup, is it possible to extend the immutability period without locking the source backup?

Also, if I could adjust the days of the week for this immutability extension process, I think I could avoid the error by not running the backup job on those days.

Is it possible to specify the day of the week as well as the interval?
https://www.veeam.com/kb4470

In addition, the backup job fails after checking the vib lock five times every 10 minutes.
Is there a way to change the number of retries or the interval?

Thank you in advance for your insights.

Re: Backup copy job takes too long to generate blocks, causing source backup job to fail

Hi Yukinobu,

Thank you very much for the detailed description and sorry to hear about the challenges. I can see the case is still on-going, so I ask you please continue with the Support Team on the investigation. If there are concerns about the processing of the case, please use the Talk to a Manager button from the case portal; this will connect you with Support Management who will review the case and adjust resources as required.

As for the issue itself, I'm not confident it's about the immutability extension alone; from your logs there, I see "Waiting for Completion" and some pretty long waits, which usually indicates insufficient resources on the server hosting the agents or potential outside interference (read: anti-virus typically). Support will review the situation a bit more closely and continue the investigation as such job schedule shuffling shouldn't be required.

A note however on QNAP S3, as you found in the topic you linked, many users have had a variety of experiences with QNAP, some of them better than others. Note the advised QNAP update and tested hardware configuration for the QNAP and compare it with your client's model, as a lesser hardware configuration will not be able to perform as well as what was tested with Veeam.
