Pre-seed another cloud destination?

Support
1

What I’m asking is somewhat like moving between cloud providers, but not quite.

I’m considering what it would take to duplicate my backups to two cloud destinations. I can think of two ways to do this:

  • Duplicati backs up to A, use a VPS with rysnc, rclone, or multicloud or similar to sync the files from A to B
  • Duplicati has two backup jobs, identical in every way except the destinations are different.

Does anyone have advice on one way or the other?

Also, if I went with the second option, I would really like to pre-seed the “B” destination with the current backup files from “A”. I’ve a few forum posts that make me think this is possible, but I haven’t seen a step by step. Is it just this?

  1. On my own, copy duplicati files from A to B.
  2. In Duplicati, create new backup job for B
  3. In Duplicati, repair the database for job B? How long will this take for ~1TB?

Both options should work. I guess it’s a matter of personal preference… 2nd option means also twice uploading of the data.

For that 2nd option: you don’t need to repair, you just need to copy the backup database of A, and in backup job B change the DB to the copy of that database.
