There are two types of data backup available for CMS:
CMSADM backup
Maintenance backup
CMS supports backups to multiple backup devices. You cannot run simultaneous backups of any type, even if multiple backup device types are administered.
CMS can back up data and restore data while data collection remains on. Backups help to minimize data loss. When a CMSADM backup starts, new login attempts from CMS Supervisor or the ASCII interface are blocked.
CMSADM backups save all local file systems, including system files and programs and CMS programs. Perform CMSADM backups after provisioning CMS or after performing an upgrade.
CMS maintenance backups save administration and historical data and the CMS data for each ACD. Avaya recommends that you do full maintenance backups weekly and incremental maintenance backups daily. You can perform maintenance backups in CMS Supervisor. A maintenance restore of CMS system administration data or ACD administration data requires CMS to be in single-user mode.
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.
