Problem with Backup

[Federico Moschini]

Dear Team,

Since yesterday when the scheduled backup on local starts we receive the following email with this log error

3CX Phone System tried to backup but failed due to the following reason(s):

System.Exception: Error creating backup ---> System.AggregateException: One or more errors occurred. (53300: sorry, too many clients already) ---> Npgsql.PostgresException: 53300: sorry, too many clients already

Hello @Federico Moschini

Please check the below thread:
