where is back being created, Is it a local backup on the pbx machine?

 

[iMark22]

SMB folder on windows server machine, it's the same folder for years... from 1 month stop working

 

[ChrisP_3CX]

does a local back up work?

the backup job was stuck
please reboot the system and try again
same trouble with FTP too slow with multiple backup at the same time

 

[iMark22]

Ok but it's the third time that i try to reboot... i will try again and i update you as soon as possible.

Hi iMark22, try this to force 3CX to create the backup locally and only then transfer to the share:

• Log in to the Management Console.
• Go to Settings -> Parameters
• Click "Add", enter the name ALWAYS_USE_TMP_FILE_FOR_BACKUP with value 1 then save.

Initiate a new backup and check if it worked.

Hi ivank with this parameters all works fine... manual and scheduled backup! Thank you!
