Why did you need to make changes to the backup file created by Discourse? Did you create manually create the tar file (on MacOS)? I’ve seen reports where it uses a different tar format which causes problems during decompression.

You might need to create a new tar file with the --format ustar option or, even better, create a new backup directly in a Discourse Docker container.

i downloaded the backup from my previous hosted discourse months back… when I located it, it was having the .tar extension (i have no clue why - I saw my emails had .tar.gz)

I will try your suggestion!
Thanks a lot @gerhard!

I’m facing the same issue and tried this. The file uploads fine, but restoration can’t find the DB dump:

[2025-01-23 18:39:45] EXCEPTION: No such file or directory @ rb_check_realpath_internal - /var/www/discourse/tmp/restores/default/2025-01-23-183945/dump.sql.gz

Any suggestions? Thanks

Hey Martim,

I see your new topic Locked out of my forum after restore, does that mean you were able to navigate this specific issue succesfully?

It does! Sorry, I thought I had deleted my comment as I managed to restore shortly after.
