Another [[special_remote|special_remotes]] that git-annex can use is
|
|
a [[special_remotes/ddar]] repository. ddar stores large file contents
|
|
in a directory structure of its own, with deduplication. For remote
|
|
repositories, ddar requires that ssh is available on the remote, with ddar also
|
|
installed remotely. When copying files to the remote, ddar only needs to send
|
|
over the network the parts of the files that are not already present remotely.
|
|
|
|
Unlike bup, ddar uses its own storage format, which allows for both creation
|
|
and deletion of de-deduplicated files.
|
|
|
|
Here's how to create a ddar remote, and describe it.
|
|
|
|
[[!template id=note text="""
|
|
Instead of specifying a remote system, you could choose to make a ddar
|
|
remote that is only accessible on the current system, by passing
|
|
"ddarrepo=/big/myddar".
|
|
"""]]
|
|
|
|
# git annex initremote myddar type=ddar encryption=none ddarrepo=example.com:/big/myddar
|
|
initremote ddar (ddar init)
|
|
Initialized empty Git repository in /big/myddar/
|
|
ok
|
|
# git annex describe myddar "my ddar repository at example.com"
|
|
describe myddar ok
|
|
|
|
Now the remote can be used like any other remote.
|
|
|
|
# git annex move my_cool_big_file --to myddar
|
|
move my_cool_big_file (to myddar...)
|
|
ok
|
|
|
|
See [[special_remotes/ddar]] for details.
