Kerio Connect supports Full backup that stores all files and items, and it also supports Differential backup that stores files that have been added or changed since the last full backup.
You can schedule any number of full and differential backups by considering the following:
- Size of the data store. The size influences the time each backup takes and its size.
- Importance of the data. When email communication and storing messages is vital for your company, schedule more frequent backups.
You can back up the following items in Kerio Connect:
- User mailboxes
- Public folders
- Mailing lists
- Configuration files
- SSL certificates
- SpamAssassin database
Any removable or network disk can be used for storing backups. Note that Temporarily disabled users are not included in the backups.
You must have full access rights to an administration, or you can use the built-in administrator account. For more information, refer to Setting access rights in Kerio Connect.
To configure the backup schedule:
In the administration interface, go to Configuration > Archiving and Backup > Backup.
Check Enable message store and configuration recovery backup.
Type a description for the backup.
Select the time and the type of backup and click OK.
Repeat steps 3-5 for additional backups.
Click Advanced and specify the maximum size and number of backups. Click OK.
In the Target backup directory section, specify the folder where to store all backups. If the network drive requires authentication, click Specify and key-in the username and password (Microsoft Windows only).No special characters allowed in the folder name.
In the Notification section, type your email address to receive notifications about backups.
If you want to make an immediate full backup, which is independent of your other backups, click the Start Now button.
Verify that the back up is being created in the scheduled time and specified target location.
Each differential backup contains the difference between the last full backup and the current data store.
With full backup from November 3, we have a differential backup on November 4, and the next differential backup on November 5 will include data difference from November 4 + November 5, so there is no point in keeping differential backup from November 4.
Kerio Connect is set up in a way that it removes old differential backups. You can change this setting in the Kerio Connect
mailserver.cfg file by changing the variable
RemoveOldDiffBackups from 1 to 0.
