MultiPar helps protect backups and transfers with error detection and recovery. The program looks at information from any number of files and folders to function as insurance against data loss. The program generates companion “PAR” files that are built from a percentage of the originals, using more space for greater protection (e.g. 10% of the original for already safe methods, 50% for frequent failures).
The program has a wide variety of customizations including format, processor usage, and various other tools available to the standard PAR format. For backups, it can also choose PAR size by available free space (e.g. saving a 3 gig file to a 4.7 gig DVD will mean generating a 1.7 gig PAR file).
Functional in Linux/Mac via WINE. The program supports multi-threading, multiple processors, can recurse subfolders, and functions with standard formats including PAR, PAR2, and (experimental) PAR3 formats.
