Hi
Synapse gave me an error while upgrade and further the restore script gave error to while upgrade. So I lost synapse all together.
To restore the app from the backup archive, I need to extract the backup tar.gz from the archive fix the error in the restore and run the restore manually.
But when I create the synapse.tar.gz from this command `$ tar czf synapse.tar.gz synapse/*` and run `$ yunohost backup restore synapse --debug` . I got this error:
```

I think whe you tar again the content you tar the directory and not the content of the directory.
info.json need to be at the root of the archive

Can you tell the command for the tar only the content of the folder in /home/yunohost.backup/archive/synapse to synapse.tar.gz ?

There are lot of my backups but synapse related files are:
```
drwxr-xr-x 3 root root 4096 May 7 18:24 synapse
-rw-r--r-- 1 root root 272 May 6 01:26 synapse-pre-upgrade2.info.json
-rw-r--r-- 1 root root 199269186 May 6 01:26 synapse-pre-upgrade2.tar.gz
-rw-r--r-- 1 root root 206604819 May 8 22:43 synapse.tar.gz
```
I have extracted synapse-pre-upgrade2.tar.gz to synapse folder, did changes in restore script and created the synapse.tar.gz as you told in above comment.

`apps backup.csv info.json`

Pour voir ce qu’il y a dans le tar gz
`tar -ztvf synapse.tar.gz | grep info.json`
?

Try to extract the info.json and put it on this path:

Are you up to date on your yunohost?

I have done it already done.
I have found the the bug. The compression is taking ./ as the path, but it should be without ./ as I see in the original backup.
`-rw-r–r-- root/root 272 2019-05-06 01:24 ./info.json`
Do you know how to tar without the ./ path ?

Follow-up of discussion on the forum : for tar, `foo` is not the same as `./foo` …
A quickfix for this is to use `tar -zcvf ../synapse.tar.gz *` instead of `tar -zcvf ../synapse.tar.gz .`
A more longterm fix is [https://github.com/YunoHost/yunohost/pull/726](https://github.com/YunoHost/yunohost/pull/726) though I don’t know how relevant it is considering this is really an edge case of “repackaging a backup archive manually”
