Description
===========

Note:

  Cyrus Backups are experimental, incomplete, and deprecated as of
  3.10.

**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, --verbose

   Increase the verbosity.  Can be specified multiple times.


Modes
=====

-f, --filename

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

-m, --mailbox

   *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, --userid

   *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.
