:hammer synctid /Backup1/Data quick
:hammer mirror-copy /Backup1/Data /Backup2/Data

:Or should i kill all the "mirror-stream" processes

    You should kill all the mirror-stream processes before doing a
    mirror-copy.  The mirroring utility is not designed to handle
    parallel feeds to the same PFS target.

:before giving the
:
:"hammer mirror-copy" command in /etc/rc.shutdown  ??
:
:also why are there 3 hammer mirror-stream processes?
:and what are the hammer-M, hammer-S* processes?
:
:Thankyou so much

    The hammer-M/S* processes are kernel helper threads for HAMMER.
    They are responsible for fsync() and flush sequencing.
