Restore from large backup

Currently having a 671GB database, 54K files, 300 versions.

Restoring takes forever, seems like hanging at “recreating database” at about 90%.

Any ideas ? Will this finish eventually ?

What version of Duplicati are you using? There is a bug in some versions that causes a database recreation to take much longer than should be required.

Apologies, not sure how I missed this reply until just now. Says you sent it 6 days ago but I was only notified recently!

Anyway - it is possible you are affected by a database recreation bug that causes it to take far longer than it’s supposed to. This bug has been fixed but the fix hasn’t made it into the beta channel yet.

If you are willing to try a canary version, you may have better luck. Be warned that the current canary release does have certain OTHER flaws not present in the beta version. Also, you won’t be able to go back to the beta version (easily) because the latest canary upgrades your databases. You’ll have to wait for the next beta release to switch back to that channel.

Similar issue was discussed recently in this thread:

Canary worked great for this user. Note the posts that talk about the flaws in the canary release so there is some added risk.


I already replied yesterday,

Per this post (in the thread I linked):

You need at least version to get the database recreation fix. Personally I would use the latest, but do not use the purge command. (I’m guessing its usage is uncommon.)

To be clear, “added in” means “still present in” on which backup corruption bug was filed., therefore “do not use the purge command” also needs “do not have any upload errors, e.g. due to Internet”, which is beyond your control. It should be fine for restores, AFAIK, but I’m kind of nervous about backups…
