BorgBackup - Backup dédupliqué
d067bc3178
a lot of speedup for: "list <repo>", "delete <repo>" list, "prune" - esp. for slow connections to remote repositories. the previous method used metadata from the archive itself, which is (in total) rather large. so if you had many archives and a slow (remote) connection, it was very slow. but there is a lot easier way: just use the archives list from the repository manifest - we already have it anyway and it also has name, id and timestamp for all archives - and that's all we need. I defined a ArchiveInfo namedtuple that has same element names as seen as attribute names of the Archive object, so as long as name, id, ts is enough, it can be used in its place. |

What is Borg?
-------------
Borg is a deduplicating 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 changes
are stored.
Borg is a fork of Attic and maintained by "The Borg Collective" (see AUTHORS file).
BORG IS NOT COMPATIBLE WITH ORIGINAL ATTIC.
UNTIL FURTHER NOTICE, EXPECT THAT WE WILL BREAK COMPATIBILITY REPEATEDLY.
THIS IS SOFTWARE IN DEVELOPMENT, DECIDE YOURSELF IF IT FITS YOUR NEEDS.
Read issue #1 on the issue tracker, goals are being defined there.
Please also see the LICENSE for more informations.
Easy to use
~~~~~~~~~~~
Initialize backup repository and create a backup archive::
$ borg init /mnt/backup
$ borg create -v /mnt/backup::documents ~/Documents
Main features
~~~~~~~~~~~~~
Space efficient storage
Variable block size deduplication is used to reduce the number of bytes
stored by detecting redundant data. Each file is split into a number of
variable length chunks and only chunks that have never been seen before are
compressed and added to the repository.
Optional data encryption
All data can be protected using 256-bit AES encryption and data integrity
and authenticity is verified using HMAC-SHA256.
Off-site backups
Borg can store data on any remote host accessible over SSH. This is
most efficient if Borg is also installed on the remote host.
Backups mountable as filesystems
Backup archives are mountable as userspace filesystems for easy backup
verification and restores.
What do I need?
---------------
Borg requires Python 3.2 or above to work.
Borg also requires a sufficiently recent OpenSSL (>= 1.0.0).
In order to mount archives as filesystems, llfuse is required.
How do I install it?
--------------------
::
$ pip3 install borgbackup
Where are the docs?
-------------------
Go to https://borgbackup.github.io/ for a prebuilt version of the documentation.
You can also build it yourself from the docs folder.
Where are the tests?
--------------------
The tests are in the borg/testsuite package. To run the test suite use the
following command::
$ fakeroot -u tox # you need to have tox installed
