amflush






amflush − flush Amanda backup files from holding disk to
tape

amflush [−b] [−f] [−−exact−match] [−s] [−D datestamp]
[−o configoption...] config [host [disk...]...]



     Amflush writes Amanda backups from the holding disks to
tape, and updates the Amanda info database and tapelist(5)
accordingly. It is similar to amdump, but does not perform
any backup operations on Amanda clients. Backups may stay in
a holding disk when something is wrong with the tape at the
time amdump is run. When this happens, the problem must be
corrected and amflush run by hand.

     The command optionally takes a set of DLE
specifications (see amanda‐match(7)) to narrow the DLEs for
which dumps will be flushed. All dumps in holding are
flushed if no expressions are given.



     −b
     Run amflush in batch mode. All datestamps are selected
     unless specified. The flush is started without
     confirmation.

     −f
     Run amflush in foreground.  Amflush normally detaches
     itself from the tty and runs as a background process.
     With the −f option, amflush stays in the foreground.
     This is useful if amflush is run as part of another
     script that, for example, advances the tape after the
     flush is completed.

     −s
     Write log to stdout/stderr instead of the amflush log
     file. Requires the −f option.

     −D datestamp
     specify a datestamp expression you want to flush; see
     amanda‐match(7) for details on the format of this
     expression.  −D 20001225−7 will flush all dumps from 25
     december 2000 to 27 december 2000.

     −−exact−match
     The host and disk are parsed as exact values

     host [disk]*
     Specify the host and disk on which the command will
     work −− see the description of DLE specifications in
     amanda‐match(7).

     −o configoption
     See the "CONFIGURATION OVERRIDE" section in amanda(8).

     You can specify many host/disk expressions, only disks
that match an expression will be flushed. All disks are
flushed if no expressions are given. see the "HOST & DISK
EXPRESSION" section of amanda(8) for a description.

     Amflush will look in the holding disks specified by the
amanda.conf file in /usr/local/etc/amanda/config for any
non−empty Amanda work directories. It then prompts you to
select a directory or to process all of the directories. The
work directories in the holding disks are named by the date
at the time amdump was run, e.g.  19910215.

     See the amanda(8) man page for more details about
Amanda.



     Amflush will search for holding areas associated with
the daily configuration. After you select which holding area
to flush, amflush writes the data to tape, updates the
databases and sends a mail report similar to amdump(8).
% amflush MyConfig
Scanning /amanda−hold...
  20001113: found Amanda directory.
  20001114: found Amanda directory.

Multiple Amanda directories, please pick one by letter:
  A. 20001113
  B. 20001114
Select directories to flush [A..B]: [ALL] all

Flushing dumps in 20001113, 20001114,
today: 20001117
to tape drive /dev/rmt/0mn.
Expecting tape DMP014 or a new tape.  (The last dumps were to tape DMP013)
Are you sure you want to do this? yes
Running in background, you can log off now.
You'll get mail when amflush is finished.

     The following example causes amflush to flush
everything to tape, then ejects tape, using 'at' to run the
task in the background.
% echo 'amflush −b −f MyConfig && mt offline' | at now



The exit code of amflush is the ORed value of:
 0  = success
 1  = error
 4  = a dle failed
 8  = Don't know the status of a dle (RESULT_MISSING in the report)

 16 = tape error or no more tape
