If you mean you want the auto backups to be saved to the 'storage point', yes ... that's been possible since version 2.x of Moodle.
Below is for Linux and for Google Bucket ... you have to translate to Windows and the actual setup of connection to the Google Bucket is outside of Moodle config. Done from operating system and Google.
A mount point on Moodle server ... like /mnt/gbucket ... has been setup. To use in Moodle:
In the /mnt/gbucket create a directory called 'autob'
The path to the location is /mnt/gbucket/autob/
In Moodle turn on File System Repo
In moodledata/repository create a symlink called 'auto' that links to /mnt/gbucket/auto/
cd /path/to/moodledata/repository/
ln -fs /mnt/gbucket/autob/ autob
Then in Moodle config,
https://site/admin/settings.php?section=automated
Set the Automated Backup Storage parameter to 'Specified Direcory for Auto Backups'
In the 'Save To' box, use the path to the symlink ....
/path/to/moodledata/repository/autob/
Suggest testing before turning on autobackup and setting a schedule by using the backup.php file in moodlecode/admin/cli/ pointed to the same symlink. And pick a known large course for testing.
