CMS Backups

[3408phonegod]

I apologize if this has been addressed before, but I couldn't find an answer by searching previous posts. My CMS System is automatically generating a backup file of some sort at 2:00am every morning. These files are being stored on the server in a directory labeled "NFS_backup". I assume these are file system backups of some sort but they are now at about 80MB daily and are starting to use a lot of diskspace.

Wondering what these file are and if I need to keep them all? If these are file system backups I should think the 3-5 most recent should be sufficient. My real question is do these file contain my CMS call history data? If so, does each file contain ALL my history, or if I want to keep 13 months of history, do I need to keep 13 months of these large files. I also noticed that each day, the new file is slightly larger than the previous day.

Looking for a little help understading what's going on here.

CMS backups seem to always be an issue. I assume your /NFS_backup directory is actually an NFS mount. This can be very dangerous if not understood and monitored. Avaya does not include any monitoring of the mount or re-mounting after the CMS or backup server are rebooted. If you run the command 'mount' you should see the NFS remote share mounted. If not, you should see if it is listed in the /etc/fstab file. If not mounted then yes your are dumping large backups onto your local drive. Run 'df -h' to see what you have for space. If you run out of disk space you will crash CMS (very bad).

Avaya only dumps the file to the mount. It is up to you to decide what you do with them. I developed a custom backup linux server to use as an NFS mount for CMS and SCP server for other servers such as CM, AAM, SM and some third party applications such as N-Focus. You might want to verify you have backups running on these also. I use custom scripts on the server and on CMS to verify the mount before the backup and to clean up old files.

CMS backups typically consist of a Full Maintenance backup and an Admin backup. Since your files are consistently large I assume you are not running any incremental backup. You need one good Full Maintenance and Admin backup if you ever have to restore. I typically keep 10 files.

The Admin backup is a manual process and recommended to be run at least once a month (or if you add a large number of new supervisors, add Avaya PSO custom interfaces, or make any significant changes to the system).
