318 # These are referred to by the disklist file. The dumptype specifies
319 # certain parameters for dumping including:
320 # auth - authentication scheme to use between server and client.
321 # Valid values are "bsd", "krb4", "krb5" and "ssh".
322 # Default: [auth bsd]
323 # comment - just a comment string
324 # comprate - set default compression rate. Should be followed by one or
325 # two numbers, optionally separated by a comma. The 1st is
326 # the full compression rate; the 2nd is the incremental rate.
327 # If the second is omitted, it is assumed equal to the first.
328 # The numbers represent the amount of the original file the
329 # compressed file is expected to take up.
330 # Default: [comprate 0.50, 0.50]
331 # compress - specify compression of the backed up data. Valid values are:
332 # "none" - don't compress the dump output.
333 # "client best" - compress on the client using the best (and
334 # probably slowest) algorithm.
335 # "client fast" - compress on the client using fast algorithm.
336 # "client custom" - compress using your custom client compression program.
337 # use client_custom_compress "PROG" to specify
338 # the custom compression program.
339 # PROG must not contain white space.
340 # "server best" - compress on the tape host using the best (and
341 # probably slowest) algorithm.
342 # "server fast" - compress on the tape host using a fast
343 # algorithm. This may be useful when a fast
344 # tape host is backing up slow clients.
345 # "server custom" - compress using your server custom compression program.
346 # use server_custom_compress "PROG" to specify
347 # the custom compression program.
348 # PROG must not contain white space.
349 # Default: [compress client fast]
350 # dumpcycle - set the number of days in the dump cycle, ie, set how often a
351 # full dump should be performed. Default: from DUMPCYCLE above
352 # estimate Determine the way AMANDA does it's estimate.
353 # "client" - Use the same program as the dumping program,
354 # this is the most accurate way to do estimates,
355 # but it can take a long time.
356 # "calcsize" - Use a faster program to do estimates, but the
357 # result is less accurate.
358 # "server" - Use only statistics from the previous run to
360 # it takes only a few seconds but the result is not
361 # accurate if your disk usage changes from day to day.
363 # encrypt - specify encryption of the backed up data. Valid values are:
364 # "none" - don't encrypt the dump output.
365 # "client" - encrypt on the client using the program specified by
366 # client_encrypt "PROG".
367 # Use client_decrypt_option to specify the decrypt-
368 # parameter, default is "-d".
369 # PROG and decrypt-parameter must not contain white space.
370 # "server" - encrypt on the server using the program specified by
371 # server_encrypt "PROG".
372 # Use server_decrypt_option to specify the decrypt-
373 # parameter, default is "-d".
374 # PROG and decrypt-parameter must not contain white space.
376 # exclude - specify files and directories to be excluded from the dump.
377 # Useful with gnutar only; silently ignored by dump and samba.
379 # "pattern" - a shell glob pattern defining which files
381 # gnutar gets --exclude="pattern"
382 # list "filename" - a file (on the client!) containing patterns
383 # re's (1 per line) defining which files to
385 # gnutar gets --exclude-from="filename"
386 # Note that the `full pathname' of a file within its
387 # filesystem starts with `./', because of the way amanda runs
388 # gnutar: `tar -C $mountpoint -cf - --lots-of-options .' (note
389 # the final dot!) Thus, if you're backing up `/usr' with a
390 # diskfile entry like ``host /usr gnutar-root', but you don't
391 # want to backup /usr/tmp, your exclude list should contain
392 # the pattern `./tmp', as this is relative to the `/usr' above.
393 # Please refer to the man-page of gnutar for more information.
394 # If a relative pathname is specified as the exclude list,
395 # it is searched from within the directory that is
396 # going to be backed up.
397 # Default: include all files
398 # holdingdisk - should the holding disk be used for this dump. Useful for
399 # dumping the holding disk itself. Default: [holdingdisk auto]
400 # "never" - Never use the holding disk.
401 # "auto" - Use the holding disk if possible.
402 # "required" - Always use the holding disk.
403 # ignore - do not back this filesystem up. Useful for sharing a single
404 # disklist in several configurations.
405 # index - keep an index of the files backed up. Default: [index no]
406 # kencrypt - encrypt the data stream between the client and server.
407 # Default: [kencrypt no]
408 # maxdumps - max number of concurrent dumps to run on the client.
409 # Default: [maxdumps 1]
410 # maxpromoteday - max number of day for a promotion, set it 0 if you don't
411 # want promotion, set it to 1 or 2 if your disk get
414 # priority - priority level of the dump. Valid levels are "low", "medium"
415 # or "high". These are really only used when Amanda has no
416 # tape to write to because of some error. In that "degraded
417 # mode", as many incrementals as will fit on the holding disk
418 # are done, higher priority first, to insure the important
419 # disks are at least dumped. Default: [priority medium]
420 # program - specify the dump system to use. Valid values are "DUMP",
421 # or "GNUTAR". Default: [program "DUMP"].
422 # record - record the backup in the time-stamp-database of the backup
423 # program (e.g. /etc/dumpdates for DUMP or
424 # @GNUTAR_LISTED_INCREMENTAL_DIRX@ for GNUTAR.).
425 # Default: [record yes]
426 # skip-full - skip the disk when a level 0 is due, to allow full backups
427 # outside Amanda, eg when the machine is in single-user mode.
428 # skip-incr - skip the disk when the level 0 is NOT due. This is used in
429 # archive configurations, where only full dumps are done and
431 # starttime - delay the start of the dump? Default: no delay
432 # strategy - set the dump strategy. Valid strategies are currently:
433 # "standard" - the standard one.
434 # "nofull" - do level 1 dumps every time. This can be used,
435 # for example, for small root filesystems that
436 # only change slightly relative to a site-wide
437 # prototype. Amanda then backs up just the
439 # "noinc" - do level 0 dumps every time.
440 # "skip" - skip all dumps. Useful for sharing a single
441 # disklist in several configurations.
442 # "incronly" - do only incremental dumps. This is similar
443 # to strategy 'nofull', but will increase
444 # the dump level as usual. Full dumps will
445 # only be performed when an 'amadmin force'
447 # Default: [strategy standard]
448 # tape_splitsize - (optional) split dump file into pieces of a specified size.
449 # This allows dumps to be spread across multiple tapes, and can
450 # potentially make more efficient use of tape space. Note that
451 # if this value is too large (more than half the size of the
452 # average dump being split), substantial tape space can be
453 # wasted. If too small, large dumps will be split into
454 # innumerable tiny dumpfiles, adding to restoration complexity.
455 # A good rule of thumb, usually, is 1/10 of the size of your
456 # tape. Default: [disabled]
457 # split_diskbuffer - (optional) When dumping a split dump in PORT-WRITE
458 # mode (usually meaning "no holding disk"), buffer the split
459 # chunks to a file in the directory specified by this option.
461 # fallback_splitsize - (optional) When dumping a split dump in PORT-WRITE
462 # mode, if no split_diskbuffer is specified (or if we somehow
463 # fail to use our split_diskbuffer), we must buffer split
464 # chunks in memory. This specifies the maximum size split
465 # chunks can be in this scenario, and thus the maximum amount
466 # of memory consumed for in-memory splitting. Default: [10m]
468 # Note that you may specify previously defined dumptypes as a shorthand way of
469 # defining parameters.
