DESCRIPTION
       An advanced disk based backup volume accumulator, geo-duplication and
       management system for HE and SME. A quick and low-cost way to make an
       environment more robust and data more accessible by archiving in
       multiple places. This replication also provides fast retrieval of
       archived data from all node hosting locations. A Perl installer creates
       the system. Nodes can be dedicated to storage or used for existing
       services over unused bandwidth. DIASER works in user space over SSH.
       The software is based on DIAP/LTASP which is a storage architecture
       designed to structure months to years of long term sustainable
       archiving space including retrospective archiving.

OPTIONS
       More than one configuration file.

       It is possible to force diaser to read a particular configuration file
       by executing ]$diaser diaser.conf --opts

       The configuration file can named as the user chooses i.e.

       ]$diaser my.config --opts


       Currently, changes will always be written to diaser.conf from the
       directory diaser was executed in. The user is free to change the name
       of the configuration file and read it into diaser as descibed above.
       This feature is particularly useful when there us more than one
       installation being managed from a single user account.

       --modify

       Apply modified settings to the running DIASER on your designated nodes.

       --numyear   years of operation required
       --startyear year to begin storing archives, this can be in the past
       --phase1    hour between 0 and 23
       --phase2    hour between 0 and 23
       --nodea     ip address in format 0.0.0.0
       --nodeb     ip address in format 0.0.0.0
       --nodec     ip address in format 0.0.0.0
       --dryrun    boolean 1(y) or 0(n)
       --lmb       lowest maximum bandwidth, KBytes per second
       --tzone_a   UTC or zeroed timezone, integer value 0-12
       --tzone_b   UTC offset against node A, integer value 0-12
       --tzone_c   UTC offset against node A, integer value 0-12
       --tout      copy time out in seconds
       --fillstarttime     time to run DIASER fill operation,
                           hour between 0 and 23
       --volumedir         the directory where your backup
                           volumes reside
       --diffconstprefix   prefix given to your Differential or
                           constant volumes
       --collectfull   are Full volumes to be collected or not,
                       boolean 1(y) or 0(n)
       --fullprefix    prefix given to your Full volumes

       --retrive

       Fetch archive data. A simple tool provided which also has additional
       command line options. The retrieval tool will walk you through a set of
       questions then list files for you to pick and transfer. The file will
       retain it's name and be located in the diaser_rel directory.

       --r_year    which year
       --r_month   which month
       --r_day     which day
       --r_full    if not a day name a full directory - leave as default
       --nodea     ip address in format 0.0.0.0
       --nodeb     ip address in format 0.0.0.0
       --nodec     ip address in format 0.0.0.0
       --porta     int
       --portb     int
       --portc     int
       --user_acc  user account name, usually default set previously
