Did the restored data folder preserve permissions?

[cd2357]

Or in other words: what was the process by which you did the backup / restore? Was it simply copying the data folder somewhere else, then copying it back? Or did you use any special flags or tools to do that?

For example, depending if the backup was done with cp or rsync, there are different flags which can preserve permissions, see https://askubuntu.com/questions/165998/how-do-i-copy-a-folder-keeping-owners-and-permissions-intact#166001

[pmartincalvo]

The backup was generated with the backup option in the client.

Then it was restored by manually copying (and overwriting previous data) with Nautilus. The user was root.

I would like to add I've executed this procedure successfully in the past. I use bisq in a live ubuntu environment with no persistence, so every time I boot I install bisq from scratch and restore the last backup this way. It's the first time I've had any trouble.

Thanks for your time

Some extra details:

Sent an END signal to the bisq process.

A few more lines appeared in the log, posting them below. They appear right after the lines I posted originally, nothing in between.
