DIAP is a set of Bash shell scripts to set up an experimental system using three backup nodes either between sites (e.g. between offices and homes) or over WANs. These could be dedicated to storage or used for existing services.
The goal is to use round robin synchronisation of incremental backup pools, where the source of data ranges from a personal laptop to a file store, over unused bandwidth where the data rate is dynamically controlled, including compression, according to load and availability. Some of the features above have been implemented, and the scripts are a toolkit to help users set up their own project as well as help the writer improve the system.
By using a number of backup nodes either between sites say between offices, homes, on a campus or over WAN's, which could be dedicated to storage or used for existing services, have a round robin synchronisation of incremental backup pools where the source of data ranges from a personal laptop to a file store over unused band-width where the data rate is dynamically controlled, including compression, according to load and availability.
The above download is an attempt to define a subset of the description on this page - a partially working prototype that hopefully has potential to expand.
The incremental data retention tuned to the needs of an organisation so that some data is always available from any node in the backup pool quickly to within a certain time frame and tape storage stations strategically places in various secure locations for older data retention. This system would avoid using prohibitively expensive packages by reusing resources, building on Open Source technologies and have a coherent strategy across many sites increasing the level of redundancy to a high degree.
With layers of indexing, accounting and central management facilities. An assumption is that individual file encryption the responsibility of the file owner, this does not rule out hard drive or partition encryption of individual nodes considered to reside at insecure locations. If used for these locations physical security automatic fail-safe measures to trigger archive deposits useless upon theft can be deployed. Similar fail-safe techniques deployed for attempted network security breaches. Virus scanners would be set to scan existing archives periodically and on entry to the archive pool.
CCTV surveillance can used to further increase the security, by deterrent and useful records of intruders. In fact the protocol itself can be used as a method to ensure integrity of the photographic records. To this end the protocol should meet necessary requirements according to the data protection act of 1998.
Referencing Long-term Archive Protocol (LTAP) I-D - Section 10 paragraph 4 and 11 (final paragraph) discusses redundancy and brokerage - it this area that DIAP may be in a position to expand or become a new I-D.
