When writing data on tape, the idea was to sync/committing to tape and
the catalog to disk every 128GiB of data. For that the counter
'bytes_written' was introduced and checked after every chunk/snapshot
archive.
Sadly we forgot to reset the counter after doing so, which meant that
after 128GiB was written onto the tape, we synced/committed after every
archive on the tape for the remaining length of the tape.
Since syncing to tape and writing to disk takes a bit of time, the drive
had to slow down every time and reduced the available throughput. (In
our tests here from ~300MB/s to ~255MB/s).
By resetting the value to zero after syncing, we avoid that and increase
throughput performance when backups are bigger than 128GiB on tape.
