This list contains the most popular data compression algorithms and tools. Mos of them are open source, an important detail if you want to preserve data for a long time from now and to be able to decompress the data in the future.
7z
Bzip2
Gzip
Zip
KGB
The best compression ratio (better than 7z), but a bit slow.
You can install it in Ubuntu with: sudo apt-get install kgb
How to:
- kgb -m file.kgb originalfile
- m is a number from 0 to 9 (lowest compression ratio from higher; higher use 1616 MB of RAM, a lot of CPU and time)
