Auto-mounting a destination

[glessard]

In the "perfect backups" blog post (https://www.shirt-pocket.com/blog/index.php/shadedgrey/comments/practices_make_perfect_backups/), you say:

"My daily backup is left unmounted but connected. SuperDuper! launches every day, mounts the drive, makes its copy, and then unmounts the backup."

How can I get a volume automatically mounted? I've tried inserting a shell script that calls diskutil to mount both partitions of my destination group (on Catalina,) but SD simply ignores it because the destination volume wasn't there to begin with. In older times I could have crudely modified the "Backup by Time" AppleScript, but that's no longer an option.

It happens automatically with a scheduled copy. Is that what you mean?

[glessard]

My scheduled copies only auto-mount their destination if the destination is a disk image. Volumes aren't getting auto-mounted -- and thus, scheduling is not useful for me unless the destination volume is always mounted.

That seems weird. I have a ton of schedules that auto-mount fine.

Do you have "Show Error" check for the schedules?

[glessard]

I unchecked it some time ago. Just to see, I checked it again and moved my schedule, and then the volume got auto-mounted when the time came. That's really not intuitive.

It's a bug that they're tied together that way, and I've already fixed it internally. That fix will be in the next release.

Nice. It might also be nice to mention/explain the auto-mounting behaviour in the "What's going to happen" text. Thanks!
