DESCRIPTION

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

OPTIONS

52       More than one configuration file.
53
54       It is possible to force diaser to read a particular configuration  file
55       by executing ]$diaser diaser.conf --opts
56
57       The configuration file can named as the user chooses i.e.
58
59       ]$diaser my.config --opts
60
61
62       Currently,  changes  will  always  be  written  to diaser.conf from the
63       directory diaser was executed in. The user is free to change  the  name
64       of  the  configuration  file and read it into diaser as descibed above.
65       This feature is particularly useful when there us more than one instal‐
66       lation being managed from a single user account.
67
68       --modify
69
70       Apply modified settings to the running DIASER on your designated nodes.
71
72       --numyear   years of operation required
73       --startyear year to begin storing archives, this can be in the past
74       --phase1    hour between 0 and 23
75       --phase2    hour between 0 and 23
76       --nodea     ip address in format 0.0.0.0
77       --nodeb     ip address in format 0.0.0.0
78       --nodec     ip address in format 0.0.0.0
79       --dryrun    boolean 1(y) or 0(n)
80       --lmb       lowest maximum bandwidth, KBytes per second
81       --tzone_a   UTC or zeroed timezone, integer value 0-12
82       --tzone_b   UTC offset against node A, integer value 0-12
83       --tzone_c   UTC offset against node A, integer value 0-12
84       --tout      copy time out in seconds
85       --fillstarttime     time to run DIASER fill operation,
86                           hour between 0 and 23
87       --volumedir         the directory where your backup
88                           volumes reside
89       --diffconstprefix   prefix given to your Differential or
90                           constant volumes
91       --collectfull   are Full volumes to be collected or not,
92                       boolean 1(y) or 0(n)
93       --fullprefix    prefix given to your Full volumes
94
95       --retrive
96
97       Fetch  archive  data.  A simple tool provided which also has additional
98       command line options. The retrieval tool will walk you through a set of
99       questions  then  list files for you to pick and transfer. The file will
100       retain it's name and be located in the diaser_rel directory.
101
102       --r_year    which year
103       --r_month   which month
104       --r_day     which day
105       --r_full    if not a day name a full directory - leave as default
106       --nodea     ip address in format 0.0.0.0
107       --nodeb     ip address in format 0.0.0.0
108       --nodec     ip address in format 0.0.0.0
109       --porta     int
110       --portb     int
111       --portc     int
112       --user_acc  user account name, usually default set previously
