imsrestore -f device|- [-a userid] [-b blocking_factor] [-c y | n]
[-e encoding [-h] [-i] [-m file] [-n] [-r file] [-s] [-t]
[-u file] [-v 0|1|2] [path]

-b blocking_factor

Indicates the blocking factor. Everything read on the device is performed by blocks of the size 512 x blocking_factor. The default is 20. Note: this number needs to be the same blocking factor that was used for the backup.

-c y | n

Provides an answer to the question: “Do you want to continue?” if an error occurs. Specify y for yes, n for no.

-e encoding

Mailbox name encoding (example: IMAP_MODIFIED-UTF-7) 

-f device|-

When -f- is specified, backup data from stdin is read. Otherwise, the backup data is read from the specified device or filename.

-h

Dumps the header. 

-g

Debug mode 

-i

Ignores existing messages. Does not check for existing messages before restore. 

Note that if you specify the -i option, you may have duplicate messages after the restore, since the -i option supersedes your ability to check for duplicates.

-m file

This mapping file is used when renaming user IDs. The format in the mapping file is oldname=newname with one set of names per line. For example:

a=xb=yc=z

where a, b, and c are old names and x, y, and z are new names.

This option is only used to rename user IDs from an older version of Messaging Server to a newer version of Messaging Server. Use the -u option for restoring users from SIMS to Messaging Server.

-n

Creates a new mailbox with a .date extension (if the mailbox exists). By default, messages are appended to the existing mailbox.

-r file

Reference file name (will restore all links in file).

-s

Used to restore a large file without using large file seeking.  

-t

Prints a table of contents, but restore is not performed. 

-u file

Specifies a backup object file. This file contains the object names (entire message store, user, group, mailbox, and so on) to restore. See name for a list of backup objects.

For restoring SIMS data into a Sun Java System Message Store, you can specify or rename users with -u file. Users should have one name per line. If you rename users, the format of file is oldname=newname with one set of names per line. For example:

joebonniejackie=jackie1

where joe and bonnie are restored, and jackie is restored and renamed to jackie1. Note that full object pathnames are not needed for user IDs.

-v [0|1|2|3|4|5]

Executes the command in verbose mode. 

0= no output

1= output at mailbox level

2= output at message level (default)

3= print meta data (for use with -t only)

4=print object level meta data (for use with -t only)

5=print the backup data of mailboxes and messages (for use with -t only)

name

Can be 1) logical pathname of the backup object, 2) user ID, 3) mailbox. See imsbackup for description.
