Aulix Backup2DVD utility does VERY VERY SUPER RELIABLE backups to optical disks like Bluray and DVD, data on backup media survives small scratches due to high redundancy
RAR - for those, who need TWO different formats of redundancy at the same time, amount of redundancy does not depend on rar usage and can be set from a command line even when using 7zip, because a second level of redundacy is provided on the whole blank level by dvdisaster.
genisoimage
dvdisaster (high redundancy of 30% at the whole medium level)
dvd+rw-format
growisofs
md5sum
dd
The program uses ssh to connect to a Linux host, it works with above programs via a network layer without direct linking which is allowed by GPL for proprietary software. It expects the open source programs at their default location as installed from their packages by default.
Features
Compresses and archives your directory by rar into multiple volumes with a file level redundancy.
Then creates ISO files contaning rar volumes.
Processes them by dvdisaster utility to add more high redundancy at the level of the whole medium.
Burns ISO images to multiple mediums.
Verifies writing results.
Backup2DVD executable (Aulix.Utils.Backup2DVD.exe) can run in any DotNet enabled environment including Windows .NET framework v2 and Mono on Linux, it has a CLI.
Backup2DVD has been tested under Debian Linux and Microsoft Windows.
On the linux host a space to hold all your compressed archives is required about triple times. Later in newer releases this can be reduced by about 2 times if needed. Following directory structure is used on the server in the $dst directory specified by the -dst command line option:
$dst/arc - here 7zip or rar volumes are created
$dst/iso - here ISO files containing compressed volumes from the previous directory are created
$dst/ecc - here dvdisaster ECC files with checksums for the ISO files from a previous directory are created
$dst/double_ecc - a second time of this program pass is applied to ECC files from the previous directory as suggested on dvdisaster website. This directory contains the same directory structure as described above with files from a second pass.
$dst/keep_on_hdd - a directory containing ECC files moved here from a second pass, it is recommended to keep them on your general daily backup storage like a network NAS, may be ZFS array, local HDD array, or at least on a simple single HDD.
Backup2DVD will save your optical backups for a duration of many years.
Aulix Backup2DVD utility combines a power of the best backup utilities available today and brings to you a convenient CLI (command line interface) to manage the whole process.
Command line interface (CLI)
-action=help | version | test_ssh | install_server | compress | format | write | verify | write_dir | process ; default: help
Actions:
help - displays a program help and license terms
version - displays a program version
test_ssh - tests SSH connection using your specified credentials
install_server - installs on your server all packages required on the server like archivers, DVD/BR writting and checksumming software from the standard repository of your server.
compress - does a single pass of compression and adding redundancy to your -src data and then places results into -dst directory
format - formats a blank inserted into your -device, also wipes out a beginning area of the blank by dd to avoid problems of writting to it new data.
write - write a single ISO file specified by -isofile option
verify - verifies a single ISO file specified by -isofile option by comparing it to a data written to a blank your -device
write_dir - writes several ISO files to several blanks, asking to insert new blanks when required
process - full cycle operation which does two passes of compresssion and adding redundacy to your data, then writes resulting ISOs one by another onto your -device, asking to change each blank when required. process - is a sequence of double compress for your -src, and then it formats, writes and verifies your blanks for each resulting ISO file.
Other Keys:
-inifile=your_inifile; default: location_of_executable/Aulix.Utils.Backup2DVD.ini the same parameters can be specified in both inifile and CLI, but CLI takes a precedence
Full cycle operation: compress a source directory into destination directory with double level of ECC as suggested by dvdisaster author and then write resulting ISOs to the specified -device
The program is available under several licenses without any warranties as stated at the end of this page :
Closed sourced program is distributed FREE OF CHARGE without any warranties.
Commercial licenses without any warranties regarding pogram usage, only delivery of corresponding files is promised. The prime cost of the program is calculated very easy, an hour of a mid level programmer costs about $75 USD, with taxes it is about $100 USD.
I have spent on this program by now about 50 hours, so the prime cost on Augest 14, 2014 is: $5000 USD. Later on it will increase as more time is spent on development, but a price of the DLL license is fixed for a duration of at least one year from now.
WITHOUT the source code. Simple NON-exclusive license which allows you compiling a closed source Aulix Backup2DVD into your own programs as an external library (DotNet/Mono DLL). WITH ONE YEAR OF UPDATES. If not prolongated after expiration you can still use your version of the program perpetually but without newer updates until purchased a prolongation for getting a new update.
It costs $29 USD per client computer. For more computers discounts are possible. For ulimited number of computers inside your organization the price is one tenth of the prime cost.
WITH the source code.Source code licenses DO NOT INCLUDE ANY UPDATES, it is just a snapshot of the souce code at the point of time when you purchase the license. Available only provided both parties sign and exchange paper copies of the license text by snail mail with a track numberlike EMS, FEDEX, DHL, USPS Priority International, etc.
Simple NON-exclusive license which provides you source code for only inhouse modfications without rights to distribute it beyond your companies boundaries.
The price of NON-exclusive is one tenth of the prime cost.
Semi-Exclusive license lets you remove this program from a public area of my website, you can license it using your own terms, for example you can distribute it under another brand or open source it under GPL.
What is kept with me:
I keep the right to be publicly known as an original author of the program
I keep the right to continue to use it at my home and any company I work or worked for (on my or my companies computers).
I keep the right to issue new licenses to 10 new customers since a Semi-Exclusive license issued to someone.
All earlier licensed users keep all their rights which were granted under their contracts, and I am allowed to continue to modify and develop my own private branch of the Backup2DVD program and issue new licenses for my newer versions of program to existing customers (including but not limited to 10 new customers) if I desire as long as needed (perpetually if I desire). But I may not distribute the program to public anymore beoynd aformentioned 10 new customers.
I keep all EXCLUSIVE rights in and to the Aulix.Common7 library and only a few fragments from it used in this program are being licensed under a SIMPLE open source license to a licensee.
The price of Semi-Exclusive license is equal to the prime cost.
