What is Attic?
|
|
|
|
--------------
|
|
|
|
Attic is a deduplicating backup program. The main goal of attic is to provide
|
|
|
|
an efficient and secure way to backup data. The data deduplication
|
|
|
|
technique used makes Attic suitable for daily backups since only actual changes
|
2013-07-05 10:32:56 +00:00
|
|
|
are stored.
|

|

|
Easy to use
|
|
|
|
~~~~~~~~~~~
|
|
|
|
Initialze backup repository and create a backup archive::
|
|
|
|
|
2013-07-08 21:38:27 +00:00
|
|
|
$ attic init /usbdrive/my-backup.attic
|
|
|
|
$ attic create -v /usbdrive/my-backup.attic::documents ~/Documents

|
|
|
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
|
2013-07-08 21:38:27 +00:00
|
|
|
attic can store data on any remote host accessible over SSH as long as
|
|
|
|
attic is installed.
