rdedup is generally similar to existing software like
zbackup, etc., with a skew towards asymmetric
encryption and synchronization friendly data model.
Thanks to Rust and solid architecture, rdedup is also exteremely performant
and very reliable (no data-loss bugs ever reported).
rdedup is written in Rust and provides both command line tool
and library API (
rdedup-lib). The library can be used to embed the core engine into other applications,
or building custom frontends and tools.
rdedup init --helpoutput for up-to-date list
renameto avoid data corruption even in case of a hardware crash)
It's written in Rust. It's a modern language, that is actually really nice to use. Rust makes it easy to have a very robust and fast software.
The author is a nice person, welcomes contributions, and helps users. Or at least he's trying... :)
rdedup currently does not implement own backup/restore functionality (own
directory traversal), and because of that it's typically paired with
rdup tools. Built-in directory traversal could improve deduplication
ratio for workloads with many small, frequently changing files.
Cloud storage integrations are missing. The architecture to support it is mostly implemented, but the actual backends are not.
If you have
cargo install rdedup
If not, I highly recommend installing rustup (think
but for Rust)
If you're interested in running
rdedup with maximum possible performance,
RUSTFLAGS="-C target-cpu=native" cargo install rdedup --vers ...
In case of troubles, check rdedup building issues or report a new one (sorry)!
rdedup -h for help.
Rdedup always operates on a repo, that you provide as an argument
--dir <DIR>), or via environment variable (eg.
rdedup init- create a new repo.
rdedup init --helpfor repository configuration options.
rdedup store <name>- store data from standard input under a given name.
rdedup load <name>- load data stored under given name and write it to standard output.
rdedup rm <name>- remove the given name.
rdedup ls- list all stored names.
rdedup gc- remove any no longer reachable data.
In combination with rdup this can be used to store and restore your backup like this:
rdup -x /dev/null "$HOME" | rdedup store home rdedup load home | rdup-up "$HOME.restored"
rdedup is data agnostic, so formats like
cpio and other will
but to get benefits of deduplication, archive format should not be
or encrypted already.
RDEDUP_PASSPHRASE is defined, it will be used
instead of interactively asking user for password.
