DIASER (Distributed Internet Archive System for Educational Repositories), based on the DIAP technology, can create back-ups in multiple locations, thus improving the environment stability and security.

- Perl v5.10.0 enabled workstation.

- 3 x Linux storage nodes (can use VM's) with root access for initial setup and Perl v5.10.0, with services; sshd, crontab, iptables ssh port open, ntpd,  rsync (non daemon).

- LAN or WAN connection between each server, the 3 machines must be able to ping one another.

- SSH server on each node, not necessarily port 22.

- Perl modules Workstation: Net::SSH::Perl, Net::SFTP, Getopt::Long and Term::ReadKey Nodes: Net::SSH::Perl i.e. as root ]#yum -y install perl-Net-SSH-Perl or cpan>install Net::SSH::Perl

- Enough disk space, see docs/worksheet_3_26_may.pdf or docs/overview.png. I'll make all this much simpler to calculate when I have finished subroutine calculate_lmb.

The file config.pl contains user settings, please edit as required.

Main settings:

number of months to years you want the system to run for start date time of daily operation node IP addresses SSH ports dry run or not time out and maximum transfer rate

Run diaser.pl -i as an ordinary user, node root passwords will be requested and make a note of your chosen diaser password.

Other options can be viewed with the diaser.pl -h switch.

Product upgrades will apply fixes and updates, use the -u switch.

This machine contains directory ad0 and aFULL01 and is your machine A. Machine A is assumed to be your most robust and closest from a network perspective to  your main backup facility. The files are assumed to be read/write by user id  diaser for the moment. Use aFull01 for your FULL copy and ad0 for all subsequent  Differentials. The script fill_diaser.sh will automate the loading of DIASER, fill_diaser will be re-written in Perl.

Currently retrieval can be achieved by manually using scp between the nodes and using rsync logs. All this will be automated.

May cause installation problems, please disable while installing.
