Description
Fixi is a command-line utility, written in Ruby, that indexes, verifies, and updates checksum information for collections of files. Tracking fixity is an important part of any digital preservation strategy, and fixi aims to help with that in as unobtrusive a manner as possible.
Fixi uses SQLite to save Fixity Information. More details, see README.
User Experiences
- Maurice de Rooij (NANETH):
- Tested Fixi on Ubuntu server (8 core Intel Xeon E5620 @2.40 GHz, 16GB RAM) using a set of 106,421 files (40 GB).
- Creating fixity took 79m34s to finish (fixi init; fixi add\;). Average speed is 22.3 files / second. Average resource use: \~800 MB (of 16GB) RAM and \~15-20 % CPU.
- Checking fixity took 29m32s to finish (fixi check\;) Average speed is 60 files/second. Average resource use: \~160 MB (of 16GB) RAM and \~50-60 % CPU.
- Creating fixity data of 106,421 files yields a SQLite database of 14 MB. Fixi uses a single thread.
- Please note that I have only tested performance. Planning to test the integrity of the fixity data soon.
