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.

52 More than one configuration file.
53 It is possible to force diaser to read a particular configuration file
55 by executing ]$diaser diaser.conf --opts
56 The configuration file can named as the user chooses i.e.
58 ]$diaser my.config --opts
60 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 --modify
69 Apply modified settings to the running DIASER on your designated nodes.
71 --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 --retrive
96 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.

103 --r_month which month
104 --r_day which day
105 --r_full if not a day name a full directory - leave as default
