zpaqfranz - versioned archiver, Swiss army knife for the serious backup and disaster recovery manager.

---

The classic archivers, such as 7z, RAR etc, are obsolete when used in the context of repeated backups (daily etc) compared to the ZPAQ technology

---

zpaqfranz manages journaling archives that conform to The ZPAQ Open Standard Format for Highly Compressed Data.
The format supports encrypted, deduplicated, and compressed single or multi-part archives with rollback capability.
It supports archives as large as 1000 times available memory or up to 250 TB and 4 billion files, interoperable between Windows and Unix/Linux.

Multiple data integrity verification systems allow great reliability.

Look especially at the examples, they are often better than a thousand words
