Appreciate if anybody can provide with estimation on the backup file created by UCM6 if backup is created using SFTP.
I need to do sizing for customer with approximately 550 users on 2 UCM 6.
that completely depends on how much config you have on your server, you could only have 550 users but 1K route patterns. I'd say it would take aprox 600 MB but the only way to do sizing would be for you do to a backup test and see the size of the tar file. this would also ensure the system is working fine and can do backups.
if this helps, please rate
