I had a client's server machine run out of disk space. They had a lot of backups stored, but I noted that the backups did not have remote container data. It seems that if the server runs out of disk space, that to protect itself, it stops doing remote container backups and only backs up the fmp12 files. This is probably something good to be done, but something I was not aware of and adds risks if you are not paying attention to backup logs and disk space. I'm assuming this is expected behavior?
