# 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 based on activity and available space.

# 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.  

# The format for a ColumnSpec is a ',' seperated list of triples.
# Each triple consists of
#   + the name of the column (as in ColumnNameStrings)
#   + prefix before the column
#   + the width of the column, if set to -1 it will be recalculated
#     to the maximum length of a line to print.
# Example:
#       "Disk=1:17,HostName=1:10,OutKB=1:7"
# or
#       "Disk=1:-1,HostName=1:10,OutKB=1:7"
#        
# You need only specify those colums that should be changed from
# the default. If nothing is specified in the configfile, the
# above compiled in values will be in effect, resulting in an
# output as it was all the time.
# The names of the colums are:
# HostName, Disk, Level, OrigKB, OutKB, Compress, DumpTime, DumpRate,
# TapeTime and TapeRate.

# 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 "/usr/adm/amanda/DailySet1/curinfo"    # database DIRECTORY
logdir   "/usr/adm/amanda/DailySet1"            # log directory
indexdir "/usr/adm/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 "/path/to/postscript/template/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.
#                 If a relative pathname is specified as the exclude list,
#                 it is searched from within the directory that is
#                 going to be backed up.
#                 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.
#                 "incronly" - do only incremental dumps. This is similar
#                              to strategy 'nofull', but will increase
#                              the dump level as usual. Full dumps will
#                              only be performed when an 'amadmin force' 
#                              has been issued 
#                 Default: [strategy standard]
#
# Note that you may specify previously defined dumptypes as a shorthand way
# of defining parameters.

    # This is quite useful for setting global parameters, so you don't have
    # to type them everywhere.  All dumptype definitions in this sample file
    # do include these definitions, either directly or indirectly.
    # There's nothing special about the name `global'; if you create any
    # dumptype that does not contain the word `global' or the name of any
    # other dumptype that contains it, these definitions won't apply.
    # Note that these definitions may be overridden in other
    # dumptypes, if the redefinitions appear *after* the `global'
    # dumptype name.
    # You may want to use this for globally enabling or disabling
    # indexing, recording, etc.  Some examples:
    # index yes
    # record no

# 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
#                         backups using this interface.  Note that if
#                         a single backup will take more than that,
#                         amanda won't try to make it run slower!
