The p7zip port of 7-Zip is several releases behind and the project seems to be abandoned. I discovered this when a large archive failed to extract with Engrampa which uses it. It reported a "Headers Error" which is due to a compatibility problem between zip format implementations. 7-Zip has a fix but the port doesn't. But there's a fork on GitHub which is being actively maintained. Check it out. Source: over 2 years ago

I use Engrampa. Which archive format I use depends on the use case. For example, if Windows users are involved, I usually use Rar archives. Under Linux, I usually use tar.xz. Source: about 3 years ago

Dar is the only tool I know of that supports incremental backups to untrusted remote storage. All the remote sees are giant encrypted blobs. Source: about 1 year ago

DAR is a linux tool that does incremental updates after a snapshot: http://dar.linux.free.fr/. Source: about 1 year ago

I have also used dar ( http://dar.linux.free.fr/ ) instead of tar for recent disk archives. Source: over 1 year ago

Dar - Like tar, but can do incremental and differential backups with rsync-style binary diffs, only archiving what's changed (and without trusting mtimes like tar --newer does). Source: almost 2 years ago

Write compressed, encrypted, sliced archives of the lvm snapshot to HDDs mounted via USB using dar Dar will pause to change HDD every few TiB. Source: about 2 years ago
