Disaster Recovery System - CUCM [ Backup Doubt ]

[pedro.alexandre]

Hello !  I hope someone here can clarify one thing for me.

I have this CUCM with its DRS Configured to make just one copy per backup.

[[{"type":"media","fid":"1416151","view_mode":"default","attributes":{"alt":"example","title":"example 1 ","height":"31","width":"505","class":"image-style-none media-element file-default","data-delta":"1"},"fields":{}}]]

When my last backup is successfully completed, my next one overwrite my last one. But if my last backup isnt successfully completed, my next backup doesnt overwrite the last corrupted one, making a new copy in the backup folder. 

My question is:  Is it a normal behavior or there is something wrong ? 

Thank you !

Yes, this is working as expected.

How do you know the previous backup is corrupt?

I would strongly recommend you change your number of backups to something greater than 1 though.

Thanks for your feedback Chris. 

I'm not sure If it's literally corrupted but it always happens when DRS says that something went wrong.  ( In Backup History, Result: Error. )

When the last backup went wrong ( Error Status ). The next one doesn't overwrite the last that was wrong.  

So, is it really expected ? Is there some Cisco documentations that speaks about it ? 

Thank you !
