7. Ejemplos de Ficheros de Configuración

A continuación listamos el resultado de nuestros ficheros de configuración: "amanda.conf" y "disklist".

7.1. "amanda.conf"


#
# amanda.conf - sample Amanda configuration file.
#
# If your configuration is called, say, "DailySet1", then this file
# normally goes in /etc/amanda/DailySet1/amanda.conf.
#
# for explanation of the parameters refer to amanda(8) and
# /usr/doc/amanda/WHATS.NEW.gz

org "Diaria"         # your organization name for reports
mailto "amanda"           # space separated list of operators at your site
dumpuser "amanda"       # the user to run dumps under
#
inparallel 4            # maximum dumpers that will run in parallel
netusage  600           # maximum net bandwidth for Amanda, in KB per sec

# a filesystem is due for a full backup once every <dumpcycle> days
dumpcycle 4 weeks       # the number of days in the normal dump cycle
tapecycle 8 tapes       # the number of tapes in rotation

bumpsize 1 MB           # minimum savings (threshold) to bump level 1 -> 2
bumpdays     1          # minimum days at each level
bumpmult     4          # threshold = bumpsize * (level-1)**bumpmult

#runtapes     9         # explained in WHATS.NEW
#tpchanger "no-changer" # the tape-changer glue script, see TAPE.CHANGERS
tapedev "no-such-device"        # Linux @ tuck, important: norewinding
rawtapedev "no-such-device"     # the raw device to be used (ftape only)
#changerfile "/mnt/amanda/changer"
changerdev "no-such-device"

tapetype DISKSAVE       # what kind of tape it is (see tapetypes below)
labelstr "^HISS[0-9][0-9]*$"    # label constraint regex: all tapes must match

diskdir "/mnt/backup"          # where the holding disk is
disksize 10 MB                  # how much space can we use on it
reserve 30
#diskdir "/dumps/amanda/work"   # additionaly holding disks can be specified
#diskdir "/mnt/disk4"
#disksize 1000 MB               #       they are used round-robin


# 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.

infofile "/var/lib/amanda/DailySet1/curinfo"    # database filename
logfile  "/var/log/amanda/DailySet1/log"        # log filename

# where the index files live
indexdir "/var/lib/amanda/DailySet1/index"

# 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.

#holdingdisk hd1 {
#    comment "main holding disk"
#    directory "/mnt/amanda1"     # where the holding disk is
#    use 30 Mb           # how much space can we use on it
#                        # a non-positive value means:
#                        #        use all space but that value
#    chunksize 1Mb       # size of chunk if you want big dump to be
#                        # dumped on multiple files on holding disks
#                        #  N Kb/Mb/Gb split images in chunks of size N
#                        #             The maximum value should be
#                        #             (MAX_FILE_SIZE - 1Mb)
#                        #  0          same as INT_MAX bytes
#}

# 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.
#
# 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.

# dumptypes
#
# These are referred to by the disklist file.  The dumptype specifies
# certain "options" for dumping including:
#       index           - keep an index of the files backed up
#       compress-fast   - (default) compress on the client using fast algorithm
#       compress-best   - compress using the best (and slowww) algorithm
#       no-compress     - don't compress the dump output
#       srvcompress     - Compress dumps on the tape host instead of client
#                         machines.  This may be useful when a fast tape host
#                         is backing up slow clients.
#       record          - (default) record the dump in /etc/dumpdates
#       no-record       - don't record the dump, for testing
#       no-hold         - don't go to the holding disk, good for dumping
#                         the holding disk partition itself.
#       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.
#       no-full         - Do a level 1 every night.  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.
#
# Also, the dumptype specifies the priority level, where "low", "medium" and
# "high" are the allowed levels.  These are only really 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 dumped first.

7.2. "disklist"


# sample Amanda2 disklist file, derived from CS.UMD.EDU's disklist
#
# If your configuration is called, say, "DailySet1", then this file
# normally goes in /etc/amanda/DailySet1/disklist.
#
# File format is:
#
#       hostname diskdev dumptype
#
# where the dumptypes are defined by you in amanda.conf.
