Avaya recommends that you back up your CMS system data monthly and your CMS ACD data daily. Running system backups is not service affecting, but the backups impact the performance of the CMS system. Therefore, ensure that you run backups when CMS system activity is low.
Caution:
If you do not perform regular backups of your data and you have a system failure, data is lost and cannot be recovered. More frequent backups increase your chances of not losing data. It is up to you to determine how much data loss you can tolerate if you choose not to back up your data more frequently.
CMS Supervisor provides options for restoring or migrating data. You can restore data from when the CMS version on the backup media is the same as the CMS version installed on the system. If the CMS versions are different, you must migrate data instead. To migrate data, navigate to . For example, if the CMS version on the backup media is r21ab.g and the CMS version installed on the system is r21ab.g, the data can be restored. If the CMS version on the backup media is r21ab.c and the CMS version installed on the system is r21ab.g, the data must be migrated.
