Restore has empty sub folders / directories

Support
#1

Hi, i recently stupidly deleted alot of files on my unraid share.
i have them backed up with encryption with duplicacy to a backblaze bucket.

i am having all sorts of trouble restoring them.

it is downloading at about 3mb/s which is slow but i get it and can put up with that but the issue is post restore.
i tried to restore the whole bucket in one go but soon learned that duplicacy has issues and stops if my internet goes down or i leave the browser accidently . . i lost alot of hours finding this out.

i then broke it down into smaller pieces. the problem then is, once that is completed, it lists the files it restored (including within subfolders) but they are not listed on the machine? all sub folders are empty.
another issue is then if i try to access the unraid share where the restores went i get a windows permission error ?? something i never have with any other share …

i am now trying again another directory with sub directorys in it to test but that will be another 4hrs.

Is there a way to download the snapshot directly from backblaze and decrypt it with the password?

using unraid 6.9.2 and duplicacy container with backblaze b2.

thank you for any help

Not sure what’s going on with empty folders (maybe permissions issue? Reapply permissions recursively) but background restore in often requested fix.

I would restore using command line tool instead. The duplicacy CLI engine is under /config/bin, the folder where to run restore from you can look up at the beginning of any backup log. Run restore in tmux session.

Also, pass -threads 10 or 20. From/To Backblaze you can expect to get up to 10Mbps per thread; it’s meant to be used multithreaded. Unless, of course, you have many small files and are simply hitting seek latency and generally poor write performance of Unraid. Check disk array queue sizes and response times during restore to confirm.

thanks alot. i will search up how to do this and hopefully it solves some of the issues.
what am i reapply permissions to? the empty folders?
thanks again.

On the theory that since duplciacy thinks those files have already been restored – they must be there; hence the folders are not empty, but rather permissions are set in a way that prevents you from seeing them. Taking ownership of those files and giving yourself read permissions should make them visible.

thanks. its unraid so there is only root? my next test did copy all the files within. so dont know why previously didnt, or why i cannot see. the windows permission thing still exists but not important as i can copy the files from the restore share to the original share which can still be accessed from windows.
i am downloading the entire snapshot from backblaze now.
can the cli take a local snapshot file and restore it? thanks again for all your help.
