                   [ -s ] objects...

DESCRIPTION

       Sync_client  is the client side of the replication system.  It runs on the client (master)
       system and connects to the target (replica) system and generates an  appropriate  sequence
       of transactions to synchronize the replica system with the master system.

OPTIONS

       -v     Verbose mode.

       -l     Verbose logging mode.

       -o     Only  attempt  to connect to the backend server once rather than waiting up to 1000
              seconds before giving up.

       -z     Enable compress.  If you set 'sync_compress'  in  the  imapd.conf  or  pass  -z  to
              sync_client, the replication protocol will attempt to enable deflate compression on
              the connection.

       -C config-file
              Read configuration options from config-file.

       -S servername
              Tells sync_client which  server  to  communicate  with.   Overrides  the  sync_host
              configuration option.

       -f input-file
              In  mailbox  or  user  replication  mode:  provides  list  of users or mailboxes to
              replicate.   In  rolling  replication  mode,  specifies  an  alternate   log   file
              (sync_client will exit after processing the log file).

       -F shutdown-file
              Rolling  replication  checks for this file at the end of each replication cycle and
              shuts down if it  is  present.  Used  to  request  nice  clean  shutdown  at  first
              convenient  point.  The  file  in  question  is  removed  on  shutdown.   Overrides
              sync_shutdown_file option in imapd.conf

       -w interval
              Wait this long before starting. Typically used so that we can attach a debugger  to
              one end of the replication system or the other.

       -t timeout
              Timeout  for  single  replication  run  in  rolling  replication.  sync_client will
              negotiate a restart after this many seconds. Default: 600 seconds

       -d delay
              Minimum delay between replication runs in rolling replication mode.  Larger  values
              provide  better efficiency as transactions can be merged.  Smaller values mean that
              the replica system is more up to date and that you don't end up with  large  blocks
              of replication transactions as a single group. Default: 3 seconds.

       -r     Rolling  (repeat)  replication  mode.  Pick  up  a  list of actions recorded by the
              lmtpd(8), imapd(8), popd(8)  and  nntpd(8)  daemons  from  the  file  specified  in
              sync_log_file.  Repeat until sync_shutdwon_file appears.

       -n     Use  the  named  channel  for  rolling  replication mode.  If multiple channels are
              specified in sync_log_channels then use one of them.  This option is probably  best
              combined with -S to connect to a different server with each channel.

       -u     User mode.  Remaining arguments are list of users who should be replicated.

       -m     Mailbox   mode.   Remaining  arguments  are  list  of  mailboxes  which  should  be
              replicated.

       -s     Sieve mode.  Remaining arguments are list of users  whose  Sieve  files  should  be
              replicated.    Principally   used   for   debugging   purposes:   not   exposed  to
              sync_client(8).
