Configuring Backup settings

To configure Backup settings:

1. In the program web interface window, select Settings → General → Backup.
2. In the Backup maximum size (MB) field, enter the total size of all messages in Backup, after which older copies of messages will start getting deleted.

   The minimum value is 1024 MB. The default value is 7168 MB (7 GB). The value of the setting must not exceed half of the free space in the /var partition on the cluster nodes.

3. In the Storage period (days) field, specify the number of days to wait before the oldest copies of messages are deleted.

   Possible values: integers from 1 to 1100 (~3 years). The default value is 30 days.

   Copies of messages are deleted based on the limit that is reached first.

4. Select an action to take for messages that need to be placed in Backup if Backup is unavailable:
   • Process messages.

     The message is processed regardless of whether it is possible to place a copy in Backup. If the Delete attachment or Disinfect action is configured, the modified message is sent to recipients after the attachment is disinfected or deleted. If the Delete message action is configured, the message is deleted without notifying the recipient. If the Reject action is configured, the message is rejected.

   • Temporary fail.

     If an error occurs while placing a copy of the message in Backup, the program returns SMTP error 451.

   • Reject messages.

     If an error occurs while placing a copy of the message in Backup, the message is rejected.

5. Click Save.

Backup is configured.
