Can I Exclude A File/Folder From Cloning?

[Mojo]

Since I recently upgraded to Yosemite I have run into a bug that affects 1Password... Copies of 1Password on permanently connected drives befuddle the software as it attempts to open the external copy; prior to Yosemite this was not an issue.

Here is the thread I started on the 1Password forum for those who are interested: https://discussions.agilebits.com/discussion/comment/231108?

I don't see a way to exclude Applications in SD! Am I missing something or must I manually delete 1Password after every backup (or until Apple fixes the bug...)?

You can eject the drive, and we - on schedule - will mount, copy and re-eject it...automatically.

[Mojo]

Dave, pardon my ignorance but I don't understand your reply...

[dnanian]

Well, as I said, eject the backup drive. A scheduled copy will automatically mount the drive, perform the copy to the drive, then eject it again.

Since the drive will therefore not be mounted (it'll be ejected), 1Password won't have a problem.

Great!

I see an SD! setting to eject a volume after a backup. But how does one prevent a single volume (or all volumes) on a connected drive from mounting at startup? And what tells a volume to mount when it's wanted for an SD! backup?

I don't know why I hadn't thought of this earlier because I really don't need one of my external drives mounted except for backups...)

(A link to the info is fine; I haven't found anything except instructions for messing with the system's hidden fstab file, and I'm not sure that I am up for that...)

[dnanian]

No doubt there's some way of keeping the drives unmounted with fstab, as you said - but it's not something I've bothered with. (I rarely restart.)

[Mojo]

So do you manually mount the partition/external drive before running SD! and then have SD! eject it after the backup is completed?

I would like to run a scheduled backup but I don't see how that is possible in this situation...

[dnanian]

No, I just leave the drive ejected, as I said. It automatically mounts, copies and ejects.

[Mojo]

So how do I leave the volume in the "ejected state?"

Perhaps the difference between you and I is that I don't leave my Mac running 24/7; I turn it off every evening. When I start it up in the morning my two connected external drives (using Firewire 800) mount all the partitions. I don't know of a way to exclude a single partition from mounting...

My apologies if I am coming across as being a bit "dense" but I'm just trying to figure out to accomplish what you describe.

I suppose that I could just leave the one drive turned off and only turn it on when I do a manual backup using SD!.

[dnanian]

My suggestion: sleep the Mac instead of turning it off.

This is great, Dave! I just got the message from 1Password as I was preparing to download its latest update. I found the solution in someone else's thread on the 1Password discussion site. I wanted to check it out though, so I searched the User Guide/Help for more about the Eject option, but I did not find it. Where do I find the documentation?

This is a more elegant solution than having SD! ignore 1Password 6.app, because it will still work when they update to 1Password 7.

[dnanian]

I think that option is newer than the guide. But it should be pretty clear. :)
