Tar's needs are pretty low, but if the pool is compressed (or if you selected a compressed TAR), that could make a big difference.  Rsync isn't going to give you any performance boost on a restore, assuming you're restoring to an empty folder:  *nothing* is going to give you a performance boost, really.  You're simply going to have to wait.

Even at 10MB/s (you wrote "mb/s", which is wrong either way, but I'm assuming you meant MegaBYTES per second, not MegaBITS per second), it will only take about 6 hours to restore.  By the time you figure out how to make it faster, it'll probably already be done!

Not to make you feel worse, but this is why you fully test a backup system INCLUDING FULL RESTORES before you put it into production.  I like to say you don't have a backup until you restore that backup.  Taking the backup is only half the process...

Something to think about when it comes to cloud-based backups.  We all know that with the magic of pooling and rsync, the first backup might take a week, but future backups will only take a few minutes.  Unfortunately, that first *restore* is going to take a week, too...  Can you wait that long?

Thanks Timothy for the great info and advice.  Much appreciated!  So using the restore from the web interface and rsync should work reliably if left over night with 200GB?  I can't see any progress bar so it is hard to tell if is even working.  It works with one small directory.  How long should it take before I start seeing folders created?
