Difference between Avaya CM backup data set and System Platform

[redyps90210]

Hi guys,

I believe someone told me this before during a training, but can you confirm what's the difference between the two backups?

On the previous older CM versions, we're just doing the CM data set backup via web GUI. But now in Aura 6.3, our vendor just configured the System platform backup (sample filename - backup_cdom-c1-date.tgz) and not for the Data set (Full Backup or via FTP).

Can you confirm if I should do it as well? I was thinking that the vendor forgot it, or the System platform covers it all.

Thanks!

With a template backup from System Platform, you can install another server with System Platform, install the template you had, and restore from that backup.

That will mostly be going away in release 7 with the move to primarily deal with VMWare.

You'll still have the XLN, OS and security backups in CM. If you were to install a new server for CM on VMWare or a new System Platform, you'd need at least the XLN backup to load on that CM.

System Platform backups, are in my opinion, not all that useful in the day-to-day stuff. When you upgrade something in System Platform - it must complete a successful backup before performing the upgrade, and in the event of failure, will restore the backup taken - that's great.

If you were going to do stuff in System Platform that you might not be able to go back from or otherwise be risky, a backup is great.

If its the 1-2 megs of CM backup in the XLN, I wouldn't count on a gig or so file of disk image snapshots to cover my back. Same for voicemail!

Thanks Kyle555!

I think I just need to set a scheduled backup for the CM's XLN, OS and security. Thanks a lot!

Good advice is to schedule XLN and OS and security differently and not do "full backups". Maybe superstition, but they're nice to have independently of one another.

Individual backups are embedded in the full backup. Below shows how to extract them
and use them individually.

This still works the same on CM virtual machine.

Below "full_My_s8500_020003_20120806.tar.gz" is a full backup file:

dadmin@My_s8500> cd ~ftp/pub
dadmin@My_s8500> mkdir temp
dadmin@My_s8500> cp full_My_s8500_020003_20120806.tar.gz temp
dadmin@My_s8500> cd temp
dadmin@My_s8500> tar xBfz full_My_s8500_020003_20120806.tar.gz
dadmin@My_s8500> du
588 ./temp/var/home/ftp/pub/.fullbackup

Doing backups from cdom is running remote shell commands on the virtual machines and collecting that data
for one backup stored on cdom.

This cdom backup will also have embedded backups that can be extracted and restored individually.
