Using GZIP leaves both compressed and uncompressed files

[CicerBro]

As per title. I set GZIP_LEVEL=9 and it gzips the files but leaves the original SQL files too.

This should not happen with the backup.sh script as it is. Please, read this:

If you see the original file is because some issue writing on the backup filesystem (maybe read-only), an interrupted compression or because the file was s symlink and only the symlink was renamed.

Nope its writing to my local Mac, can write from the container just fine. Nothing got interrupted or linked.

Running the backup script inside the container seems to work and leave behind a "latest" symlink, but running it on stop EXIT_BACKUP=1 just gives me both .sql, the .sql.gz and no symlink.

ok, you didn't mention the EXIT_BACKUP=1 before ... can you please share the docker-compose or at least the values of the environment variables you use to reproduce this?

maybe the error is because the backup.sh process is interrupted on exit so can you also check changes in this branch?
