How to enable debug mode for Plesk backup operations

Question

How to enable debug mode for Plesk backup operations?

Answer

For backup tasks that are performed in Plesk Backup Manager

Nothing needs to be done. Logs are collected with debug mode enabled by default.

For scheduled backup tasks

To increase verbosity for scheduled Plesk backups, enable the verbose_scheduled_backup_logs parameter in the Plesk database using the following command:

To enable debug, run:

# plesk db “REPLACE INTO misc (param,val) VALUES (‘verbose_scheduled_backup_logs’, ‘true’)”

Warning: It is strongly recommended to disable verbosity once the troubleshooting is finished.
To turn debug off, run:

# plesk db “DELETE FROM misc WHERE param=’verbose_scheduled_backup_logs'”

For the ‘pleskbackup’ command-line utility

Add one or more verbose -v options to the command.

For example, the following commands will back up the whole server with maximum verbosity in logs and output in a command-line interface:

on Linux:

# /usr/local/psa/bin/pleskbackup server -vvvvv
on Windows Server, multiple verbose options cannot be joined and have to be specified separately:

C:> “%plesk_cli%pleskbackup” –server -v -v -v -v -v

Additional debug logging for pmmcli-rc utility

In addition to debug mode mentioned above, enable debug mode:

Open the pmmcli-rc file in a text editor (create a new one if it does not exist):
- on Linux:
```
/usr/local/psa/admin/share/pmmcli/pmmcli-rc
```
- on Windows Server:
```
C:Program Files (x86)Pleskadminsharepmmclipmmcli-rc
```
Change the value of the FORCE_DEBUG_LOG parameter from 0 to 1:
```
FORCE_DEBUG_LOG 1
```
Save the changes and close the file.

Warning: It is strongly recommended to disable debug (remove the line above from the file) once the troubleshooting is finished.

on Linux:
- /var/log/plesk/PMM/ in Plesk Obsidian
- /usr/local/psa/PMM/logs/ in Plesk Onyx
