It would be great to be able to choose where the backup location is for the post upgrade task of Portal upgrades, including network drives.
Reason 1 - it is not obvious where this location is if the content, db, index and temp directories have been moved to another drive. So we may think it'll be backup up to where these are located, when it gets backed up on c: instead.
Reason 2 - Often times there's no other need to increase disk space other than to perform the upgrade. It is not ideal to have to pay for the extra space when it's operationally not needed. And if we are to reduce the disk space again, it is often not straight forward.
With this option, we could either:
- easily add a temp drive to the machine, then select this drive as the backup location. When the upgrade is over, the drive can simply be dropped.
- Set a location on a network drive that has enough capacity to store the backup files, which could then be deleted after the upgrade.
The above 2 options can be achieved manually when using the REST API (https://developers.arcgis.com/rest/enterprise-administration/portal/upgrade/) but we still need to set isBackupRequired = False and isRollbackRequired = False. If we can set the backup location as an option as part of the post upgrade task, we would also be able to set isBackupRequired and isRollbackRequired to True.
