DESCRIPTION

       cyr_backup is a tool for inspecting the contents of a Cyrus backup.

       cyr_backup  reads its configuration options out of the imapd.conf(5) file unless specified
       otherwise by -C.

       In all invocations, backup is interpreted according to  the  specified  MODE.   See  Modes
       below.

       cyr_backup provides the following sub-commands:

       list

              cyr_backup [OPTIONS] [MODE] backup list chunks
              cyr_backup [OPTIONS] [MODE] backup list mailboxes
              cyr_backup [OPTIONS] [MODE] backup list messages
              cyr_backup [OPTIONS] [MODE] backup list all

              List chunks, mailboxes, or messages contained in backup.

       show

              cyr_backup [OPTIONS] [MODE] backup show mailboxes [ mboxname | uniqueid ]...
              cyr_backup [OPTIONS] [MODE] backup show messages guid...

              show  mailboxes  shows  the  contents  (i.e.  the  contained messages) of mailboxes
              matching each given mboxname or uniqueid in the named backup.   The  uid,  expunged
              time, and guid of each message are shown.

              show  messages  shows  details  of  messages  matching each given guid in the named
              backup.  The guid, containing mailboxes, and  MIME  headers  of  each  message  are
              shown.

       dump

              cyr_backup [OPTIONS] [MODE] backup dump chunk id
              cyr_backup [OPTIONS] [MODE] backup dump message guid

              Dump  the  contents of the specified chunk or message contained in the named backup
              to standard out.  Chunks are output as uncompressed backup data format (which is  a
              replication  protocol  stream).   Messages  are  output  in  their  on-disk  format
              (typically MIME).

              dump chunk is mainly useful for diagnostic purposes.

              dump message may be useful as part of a manual message  restoration  process,  when
              the restoration destination does not support the restore(8) command.

       json

              cyr_backup [OPTIONS] [MODE] backup json chunks
              cyr_backup [OPTIONS] [MODE] backup json mailboxes
              cyr_backup [OPTIONS] [MODE] backup json messages
              cyr_backup [OPTIONS] [MODE] backup json headers guid...

              Dump  information  about  the  chunks, mailboxes or messages contained in the named
              backup to standard out, in JSON format.

OPTIONS

       -C config-file
              Use  the  specified  configuration  file  config-file  rather  than   the   default
              imapd.conf(5).

       -v     Increase the verbosity.  Can be specified multiple times.

MODES

       -f     backup  is  interpreted  as  a  filename.  The named file does not need to be known
              about in the backups database.

       -m     backup is interpreted as a mailbox name.  There must be a known backup for the user
              whose mailbox this is.

              Known  backups  are  recorded  in  the  database  specified  by  the  backup_db and
              backup_db_path configuration options.

       -u     backup is interpreted as a userid.  There must be a known backup for the  specified
              user.

              This is the default if no mode is specified.
