[CE 15.6.0] [Docker] [OSX] gitlab-backup fails to create a tar archive

Hi! We are struggling to make backup working on CE docker installation on a macos machine (is running docker gitlab on OSX supported in any way?)

The creating of the tar archive fails without any particular error. It has some “file changed as we read it” before failing, and that’s it.

the command. It runs to completion with repositories excluded, but fails otherwise with a lot of repository data (~30Gb)

docker exec -t <CONTAINER_ID> gitlab-backup create STRATEGY=copy GZIP_RSYNCABLE=yes

stdout from the command
