Never Finished - [ERROR] #0 /usr/local/jetapps/var/lib/jetbackup5

Post by ldewinne »

Good morning,
I have 2 sites that don't backup nicely and get a failed one after 2 hours. The rest of the websites do make backups. See a piece of log below. Anyone have a solution?

OS : CloudLinux v8.9.0
Jetbackup : Base Version 5.3.9 Panel Version 5.3.9

Hello ldewinne,

Can you please share what destination type (and provider if applicable) you are using?

As an initial troubleshooting step, you can try lowering the number of "Maximum concurrent Threads" if the destination is using or jetindex engine (non-legacy destination). You can also try reducing the number of Concurrent Backup/Clone Tasks in Settings >> Performance.

Our helpdesk is available 24/7/365 and you can contact us by emailing [email protected] if you want us to take a closer look.

Best regards,

Hello,
I make my backup to a NAS via FTP.
Last night I adjusted the installations but the problem still remains.
The problem is only on 2 sites, the other websites run fine.

Concurrent System Tasks

3
Task(s)
Set the maximum number of concurrent system tasks that may run simultaneously. JetBackup utilizes one fork per system task on the server. (Maximum value of 10)
NOTE: Higher value doesn't necessarily mean higher performance, we recommend 1 task per server CPU core, but no more than 5 for daily usage, and 10 for restoring in a disaster recovery mode.

Concurrent Restore/Download/Reindex Tasks

3
Task(s)
Set the maximum number of concurrent restore/download/reindex tasks that may run simultaneously. JetBackup utilizes one fork per restore/download task on the server. (Maximum value of 10)
NOTE: Higher value doesn't necessarily mean higher performance, we recommend 1 task per server CPU core, but no more than 5 for daily usage, and 10 for restoring in a disaster recovery mode.

Concurrent Backup/Clone Tasks

3
Task(s)
Set the maximum number of concurrent backup/clone tasks that may run simultaneously. JetBackup utilizes one fork per Directories Backup Job or one fork per account on an Account Backup/Clone Job. (Maximum value of 10)
NOTE: Higher value doesn't necessarily mean higher performance, we recommend 1 task per server CPU core, but no more than 5. You also need to consider limiting CPU usage (200% is a reasonable limit).

Hello Idewinne,

Kindly attempt to reduce the destination Concurrent Threads value by navigating to JetBackup 5 >> Destination >> Manage Destination >> Maximum Concurrent Threads. Additionally, please turn on debug so we can get more clues on this error. You can do this by accessing JetBackup 5 >> Settings >> Debug Active.

If the error persists, feel free to open a ticket with us. We have a technical support team available 24/7/365 to help you with your JetBackup related support issues.

Best Regards
