setting a custom directory for restore

Alex JOST    Jul 28 2:35PM 2017 CLI

I'm new to duplicacy and having a hard time wrapping my head around the restore procedure. As far as I understood the only way to restore files is to either use 'duplicacy restore -overwrite' and overwrite every single file of that snapshot in place, or I can cat single files into a custom directory. The last method requires that I know the absolute path of the files I want to restore.

Is there no way to mount a snapshot or restore it to a custom directory so I can browse and handpick the files/directories I want to restore?

You can restore to a different directory as long as you use the same repository id.

cd path\to\restore
duplicacy init original_repository_id storage_url
duplicacy restore -r 1 files_to_be_restored

This works even on a different computer. All Duplicacy cares is the repository id -- repositories with the same id act like the same repository no matter where they are.

Thanks for the fast reply, I will try that out as soon as I have time.

May I still suggest adding a way to mount a snapshot. It makes skimming through the snapshot easy and doesn't require to have disk space left on the device.

I made some snapshots of multiple repositories of a system. When restoring a snapshot (to a diferrent directory) I compared the content and found a lot of files missing. I'm trying to list every step, hoping you spot some obvious mistake.

root@m1:/etc# cat .duplicacy/preferences

        "id": "m1-etc",

        "no_restore": false,
        "no_save_password": false,
        "keys": null
    }

Can you run duplicacy list -r 3 --files to see if those files are in the backup?


Alex JOST    Jul 29 1:20PM 2017

I think I know now what's going on. Looks like duplicacy omits directories when they are empty. Sorry for not realizing that earlier, but that's a ratter weird behavior.


gchen    Jul 29 7:10PM 2017

Maybe that was a bad decision. A few others complained about that in the past. I'll fix it next week.


Alex JOST    Jul 30 12:31PM 2017

Glad to hear that. Thanks!

The fix to restore empty directories has been checked in to the github branch. It will get into version 2.0.7.
