132 # The advantages include: tape drive is more likely to operate in streaming

135 # The main disadvantage is that dumps on the holding disk need to be flushed

204 # Amanda needs a few Mb of diskspace for the log and debug files,

207 # Create an amanda directory under there. You need a separate infofile and
208 # logdir for each configuration, so create subdirectories for each conf and
209 # put the files there. Specify the locations below.

223 # Define the type of tape you use here, and use it in "tapetype"

225 # tells amanda how many MB will fit on the tape, how big the filemarks
226 # are, and how fast the tape device is.
228 # A filemark is the amount of wasted space every time a tape section
229 # ends. If you run `make tapetype' in tape-src, you'll get a program
230 # that generates tapetype entries, but it is slow as hell, use it only

328 # These are referred to by the disklist file. The dumptype specifies
329 # certain parameters for dumping including:
330 # auth - authentication scheme to use between server and client.
331 # Valid values are "bsd" and "krb4". Default: [auth bsd]
332 # comment - just a comment string
333 # comprate - set default compression rate. Should be followed by one or
334 # two numbers, optionally separated by a comma. The 1st is
335 # the full compression rate; the 2nd is the incremental rate.
336 # If the second is omitted, it is assumed equal to the first.
337 # The numbers represent the amount of the original file the
338 # compressed file is expected to take up.
339 # Default: [comprate 0.50, 0.50]
340 # compress - specify compression of the backed up data. Valid values are:
341 # "none" - don't compress the dump output.
342 # "client best" - compress on the client using the best (and
343 # probably slowest) algorithm.
344 # "client fast" - compress on the client using fast algorithm.
345 # "server best" - compress on the tape host using the best (and
346 # probably slowest) algorithm.
347 # "server fast" - compress on the tape host using a fast
348 # algorithm. This may be useful when a fast
349 # tape host is backing up slow clients.
350 # Default: [compress client fast]
351 # dumpcycle - set the number of days in the dump cycle, ie, set how often a
352 # full dump should be performed. Default: from DUMPCYCLE above
353 # exclude - specify files and directories to be excluded from the dump.
354 # Useful with gnutar only; silently ignored by dump and samba.
356 # "pattern" - a shell glob pattern defining which files
358 # gnutar gets --exclude="pattern"
359 # list "filename" - a file (on the client!) containing patterns
360 # re's (1 per line) defining which files to
362 # gnutar gets --exclude-from="filename"
363 # Note that the `full pathname' of a file within its
364 # filesystem starts with `./', because of the way amanda runs
365 # gnutar: `tar -C $mountpoint -cf - --lots-of-options .' (note
366 # the final dot!) Thus, if you're backing up `/usr' with a
367 # diskfile entry like ``host /usr gnutar-root', but you don't
368 # want to backup /usr/tmp, your exclude list should contain
369 # the pattern `./tmp', as this is relative to the `/usr' above.
370 # Please refer to the man-page of gnutar for more information.
371 # If a relative pathname is specified as the exclude list,
372 # it is searched from within the directory that is
373 # going to be backed up.
374 # Default: include all files
375 # holdingdisk - should the holding disk be used for this dump. Useful for
376 # dumping the holding disk itself. Default: [holdingdisk yes]
377 # ignore - do not back this filesystem up. Useful for sharing a single
378 # disklist in several configurations.
379 # index - keep an index of the files backed up. Default: [index no]
380 # kencrypt - encrypt the data stream between the client and server.
381 # Default: [kencrypt no]
382 # maxdumps - max number of concurrent dumps to run on the client.
383 # Default: [maxdumps 1]
384 # maxpromoteday - max number of day for a promotion, set it 0 if you don't
385 # want promotion, set it to 1 or 2 if your disk get
388 # priority - priority level of the dump. Valid levels are "low", "medium"
389 # or "high". These are really only used when Amanda has no
390 # tape to write to because of some error. In that "degraded
391 # mode", as many incrementals as will fit on the holding disk
392 # are done, higher priority first, to insure the important
393 # disks are at least dumped. Default: [priority medium]
394 # program - specify the dump system to use. Valid values are "DUMP" and
395 # "GNUTAR". Default: [program "DUMP"].
396 # record - record the backup in the time-stamp-database of the backup
397 # program (e.g. /etc/dumpdates for DUMP or
398 # @GNUTAR_LISTED_INCREMENTAL_DIRX@ for GNUTAR.).
399 # Default: [record yes]
400 # skip-full - skip the disk when a level 0 is due, to allow full backups
401 # outside Amanda, eg when the machine is in single-user mode.
402 # skip-incr - skip the disk when the level 0 is NOT due. This is used in
403 # archive configurations, where only full dumps are done and
405 # starttime - delay the start of the dump? Default: no delay
406 # strategy - set the dump strategy. Valid strategies are currently:
407 # "standard" - the standard one.
408 # "nofull" - do level 1 dumps every time. This can be used,
409 # for example, for small root filesystems that
410 # only change slightly relative to a site-wide
411 # prototype. Amanda then backs up just the
413 # "noinc" - do level 0 dumps every time.
414 # Unfortunately, this is not currently
415 # implemented. Use `dumpcycle 0'
417 # "skip" - skip all dumps. Useful for sharing a single
418 # disklist in several configurations.
419 # "incronly" - do only incremental dumps. This is similar
420 # to strategy 'nofull', but will increase
421 # the dump level as usual. Full dumps will
422 # only be performed when an 'amadmin force'
424 # Default: [strategy standard]
426 # Note that you may specify previously defined dumptypes as a shorthand way
427 # of defining parameters.
