#
# amanda.conf - sample Amanda configuration file.  This started off life as
#               the actual config file in use at CS.UMD.EDU.
#
# If your configuration is called, say, "csd", then this file normally goes
# in /etc/amanda/csd/amanda.conf.
#

mailto "amanda"		# space separated list of operators at your site
dumpuser "amanda"	# the user to run dumps under

dumpcycle 4 weeks	# the number of days in the normal dump cycle
runspercycle 20         # the number of amdump runs in dumpcycle days
			# (4 weeks * 5 amdump runs per week -- just weekdays)
tapecycle 25 tapes	# the number of tapes in rotation
			# 4 weeks (dumpcycle) times 5 tapes per week (just
			# the weekdays) plus a few to handle errors that
			# need amflush and so we do not overwrite the full
			# backups performed at the beginning of the previous

# Specify tape device and/or tape changer.  If you don't have a tape
# changer, and you don't want to use more than one tape per run of
# amdump, just comment out the definition of tpchanger.

# Some tape changers require tapedev to be defined; others will use
# their own tape device selection mechanism.  Some use a separate tape
# changer device (changerdev), others will simply ignore this
# parameter.  Some rely on a configuration file (changerfile) to
# obtain more information about tape devices, number of slots, etc;
# others just need to store some data in files, whose names will start
# with changerfile.  For more information about individual tape
# changers, read docs/TAPE.CHANGERS.

# At most one changerfile entry must be defined; select the most
# appropriate one for your configuration.  If you select man-changer,
# keep the first one; if you decide not to use a tape changer, you may
# comment them all out.

# Specify holding disks.  These are used as a temporary staging area for
# dumps before they are written to tape and are recommended for most sites.
# The advantages include: tape drive is more likely to operate in streaming
# mode (which reduces tape and drive wear, reduces total dump time); multiple
# dumps can be done in parallel (which can dramatically reduce total dump time.
# The main disadvantage is that dumps on the holding disk need to be flushed
# (with amflush) to tape after an operating system crash or a tape failure.
# If no holding disks are specified then all dumps will be written directly
# to tape.  If a dump is too big to fit on the holding disk than it will be
# written directly to tape.  If more than one holding disk is specified then
# they will all be used round-robin.

# If amanda cannot find a tape on which to store backups, it will run
# as many backups as it can to the holding disks.  In order to save
# space for unattended backups, by default, amanda will only perform
# incremental backups in this case, i.e., it will reserve 100% of the
# holding disk space for the so-called degraded mode backups.
# However, if you specify a different value for the `reserve'
# parameter, amanda will not degrade backups if they will fit in the
# non-reserved portion of the holding disk.

# reserve 30 # percent


# This means save at least 30% of the holding disk space for degraded
# mode backups.  

# Amanda needs a few Mb of diskspace for the log and debug files,
# as well as a database.  This stuff can grow large, so the conf directory
# isn't usually appropriate.  Some sites use /usr/local/var and some /usr/adm.
# Create an amanda directory under there.  You need a separate infofile and
# logdir for each configuration, so create subdirectories for each conf and
# put the files there.  Specify the locations below.

# Note that, although the keyword below is infofile, it is only so for
# historic reasons, since now it is supposed to be a directory (unless
# you have selected some database format other than the `text' default)
infofile "/var/lib/amanda/DailySet1/curinfo"	# database DIRECTORY
logdir   "/var/lib/amanda/DailySet1"		# log directory
indexdir "/var/lib/amanda/DailySet1/index"	# index directory
#tapelist "/usr/adm/amanda/DailySet1/tapelist"	# list of used tapes
# tapelist is stored, by default, in the directory that contains amanda.conf


# tapetypes

# Define the type of tape you use here, and use it in "tapetype"
# above.  Some typical types of tapes are included here.  The tapetype
# tells amanda how many MB will fit on the tape, how big the filemarks
# are, and how fast the tape device is.

# A filemark is the amount of wasted space every time a tape section
# ends.  If you run `make tapetype' in tape-src, you'll get a program
# that generates tapetype entries, but it is slow as hell, use it only
# if you really must and, if you do, make sure you post the data to
# the amanda mailing list, so that others can use what you found out
# by searching the archives.

# For completeness Amanda should calculate the inter-record gaps too,
# but it doesn't.  For EXABYTE and DAT tapes this is ok.  Anyone using
# 9 tracks for amanda and need IRG calculations?  Drop me a note if
# so.

# If you want amanda to print postscript paper tape labels
# add a line after the comment in the tapetype of the form
#    lbl-templ "/usr/share/amanda/label.ps"

# if you want the label to go to a printer other than the default
# for your system, you can also add a line above for a different
# printer. (i usually add that line after the dumpuser specification)

# dumpuser "operator"     # the user to run dumps under
# printer "mypostscript"  # printer to print paper label on

# dumptypes
#
# These are referred to by the disklist file.  The dumptype specifies
# certain parameters for dumping including:
#   auth	- authentication scheme to use between server and client.
#		  Valid values are "bsd" and "krb4".  Default: [auth bsd]
#   comment	- just a comment string
#   comprate	- set default compression rate.  Should be followed by one or
#		  two numbers, optionally separated by a comma.  The 1st is
#		  the full compression rate; the 2nd is the incremental rate.
#		  If the second is omitted, it is assumed equal to the first.
#		  The numbers represent the amount of the original file the
#		  compressed file is expected to take up.
#		  Default: [comprate 0.50, 0.50]
#   compress	- specify compression of the backed up data.  Valid values are:
#		  "none"        - don't compress the dump output.
#		  "client best" - compress on the client using the best (and
#				  probably slowest) algorithm.
#		  "client fast" - compress on the client using fast algorithm.
#		  "server best" - compress on the tape host using the best (and
#				  probably slowest) algorithm.
#		  "server fast" - compress on the tape host using a fast
#				  algorithm.  This may be useful when a fast
#				  tape host is backing up slow clients.
#		  Default: [compress client fast]
#   dumpcycle	- set the number of days in the dump cycle, ie, set how often a
#		  full dump should be performed.  Default: from DUMPCYCLE above
#   exclude	- specify files and directories to be excluded from the dump.
#		  Useful with gnutar only; silently ignored by dump and samba.
#		  Valid values are:
#		  "pattern"       - a shell glob pattern defining which files
#				    to exclude.
#				    gnutar gets --exclude="pattern"
#		  list "filename" - a file (on the client!) containing patterns
#				    re's (1 per line) defining which files to
#				    exclude.
#				    gnutar gets --exclude-from="filename"
#		  Note that the `full pathname' of a file within its
#		  filesystem starts with `./', because of the way amanda runs
#		  gnutar: `tar -C $mountpoint -cf - --lots-of-options .' (note
#		  the final dot!)  Thus, if you're backing up `/usr' with a
#		  diskfile entry like ``host /usr gnutar-root', but you don't
#		  want to backup /usr/tmp, your exclude list should contain
#		  the pattern `./tmp', as this is relative to the `/usr' above.
#		  Please refer to the man-page of gnutar for more information.
#		  Default: include all files
#   holdingdisk	- should the holding disk be used for this dump.  Useful for
#		  dumping the holding disk itself.  Default: [holdingdisk yes]
#   ignore	- do not back this filesystem up.  Useful for sharing a single
#		  disklist in several configurations.
#   index	- keep an index of the files backed up.  Default: [index no]
#   kencrypt	- encrypt the data stream between the client and server.
#		  Default: [kencrypt no]
#   maxdumps	- max number of concurrent dumps to run on the client.
#		  Default: [maxdumps 1]
#   priority	- priority level of the dump.  Valid levels are "low", "medium"
#		  or "high".  These are really only used when Amanda has no
#		  tape to write to because of some error.  In that "degraded
#		  mode", as many incrementals as will fit on the holding disk
#		  are done, higher priority first, to insure the important
#		  disks are at least dumped.  Default: [priority medium]
#   program	- specify the dump system to use.  Valid values are "DUMP" and
#		  "GNUTAR".  Default: [program "DUMP"].
#   record	- record the dump in /etc/dumpdates.  Default: [record yes]
#   skip-full	- skip the disk when a level 0 is due, to allow full backups
#		  outside Amanda, eg when the machine is in single-user mode.
#   skip-incr	- skip the disk when the level 0 is NOT due.  This is used in
#		  archive configurations, where only full dumps are done and
#		  the tapes saved.
#   starttime	- delay the start of the dump?  Default: no delay
#   strategy	- set the dump strategy.  Valid strategies are currently:
#		  "standard" - the standard one.
#		  "nofull"   - do level 1 dumps every time.  This can be used,
#			       for example, for small root filesystems that
#			       only change slightly relative to a site-wide
#			       prototype.  Amanda then backs up just the
#			       changes.
#		  "noinc"    - do level 0 dumps every time.
#			       Unfortunately, this is not currently
#			       implemented.  Use `dumpcycle 0'
#			       instead.
#		  "skip"     - skip all dumps.  Useful for sharing a single
#			       disklist in several configurations.
#		  Default: [strategy standard]
#
# Note that you may specify previously defined dumptypes as a shorthand way
# of defining parameters.

# network interfaces
#
# These are referred to by the disklist file.  They define the attributes
# of the network interface that the remote machine is accessed through.
# Notes: - netusage above defines the attributes that are used when the
#          disklist entry doesn't specify otherwise.
#        - the values below are only samples.
#        - specifying an interface does not force the traffic to pass
#          through that interface.  Your OS routing tables do that.  This
#          is just a mechanism to stop Amanda trashing your network.
# Attributes are:
#	use		- bandwidth above which amanda won't start

#			  amanda won't try to make it run slower!
