Doubts with UrBackup: Queries, Backup Logs, Linux Error, and Fixed Scheduling

Hello everyone, I have some doubts and need some tips:

01 - I migrated three of my clients to my private cloud, where I’m using UrBackup. I configured it and I’m receiving logs after each backup. However, I need to inform each client about their own results. In other words, when client01 performs a backup, the UrBackup server should send an email to client01 and so on.

02 - One of these clients has a Linux server and is encountering an error even after the backup is completed. The file I’m backing up is a daily updated database dump on an NFS.

03 - One of the clients would like the backup to run at specific times twice a day, at 12:00 and 18:00. This was possible in another tool we used before. Is it possible to set exact times for backup?

1 out of 3 is resolved. In the case of each client’s backup, we need to send the log to their own email. First, create a user account and associate this backup task with it. Log in with this user and, in the logs section, add the email account where we want to receive logs from this client.
