borgbackup - 1.4.0-4 main

Borg is a deduplicating and compressing backup program. Optionally, it
also supports authenticated encryption. It was forked from the attic
backup program.
.
The main goal of Borg is to provide an efficient and secure way to
backup data. The data deduplication technique used makes Borg suitable
for daily backups since only the changes are stored. The authenticated
encryption makes it suitable for backups to not fully trusted targets.
.
It can push backups to remote repositories accessed via ssh. A client
pushing a backup invokes "borg serve" on the repository host. It is
possible to restrict the ssh key to "borg serve" using the
authorized_keys command= clause.
.
Please note that the server and the client should be on the same
version of borgbackup. Using different versions of borgbackup on
client and server might result in 'incompatible API version' error
messages and a non-working backup.
.
While there is no direct operations mode for pull-type backups, you
can configure the backup target in append-only mode, preventing the
backup source from deleting or altering previous backups.
