I'm not familiar with compression very much, what's the difference between what 7z does versus "archive recovery"? Thanks

- nguyenkien 5y agoWinrar save extra information to the compressed file. So in case your .rar file damage, it can be recovered.

- smarx007 5y agoYou'd need to use a tool like par2 (https://en.wikipedia.org/wiki/Parchive https://en.wikipedia.org/wiki/Parchive) on top of a 7z file to get a recovery record.
- deelowe 5y agoSome compression formats are actually designed for data archival and compression. Rar is one such format. One of the early use cases was data archival onto long term storage mediums such as tape. As such, it has built in parity which means you can recover partially corrupted archives. It can also do things like split the archive up over many smaller files. Again, because this sort of thing was needed for backing up to tape, floppy, etc in the late 90s/early 2ks.
