We've seen above that git-annex can be used to store files in
|
||
|
|
regular git remotes, accessed either via ssh, or on a removable drive. But
|
||
|
|
git-annex can also store files in Amazon S3, Glacier, on a rsync server, in
|
||
|
|
WebDAV, or even pull files down from the web and bittorrent.
|
||
|
|
This and much more is made possible by [[special_remotes]].
|
||
|
|
|
||
|
|
These are not normal git repositories; indeed the git repository is not
|
||
|
|
stored on a special remote. But git-annex can store the contents of files
|
||
|
|
in special remotes, and operate on them much as it would on any other
|
||
|
|
remote. Bonus: Files stored on special remotes can easily be
|
||
|
|
[[encrypted|encryption]]!
|
||
|
|
|
||
|
|
All you need to get started using a special remote is to initialize it.
|
||
|
|
This is done using the `git annex initremote` command, which needs to be
|
||
|
|
passed different parameters depending on the type of special remote.
|
||
|
|
|
||
|
|
Some special remotes also need things like passwords to be set in
|
||
|
|
environment variables. Don't worry -- it will prompt if you leave anything off.
|
||
|
|
So feel free to make any kind of special remote instead of the S3 remote
|
||
|
|
used in this example.
|
||
|
|
|
||
|
|
# export AWS_ACCESS_KEY_ID="somethingotherthanthis"
|
||
|
|
# export AWS_SECRET_ACCESS_KEY="s3kr1t"
|
||
|
|
# git annex initremote mys3 type=S3 chunk=1MiB encryption=shared
|
||
|
|
initremote mys3 (shared encryption) (checking bucket) (creating bucket in US) ok
|
||
|
|
|
||
|
|
Now you can store files on the newly initialized special remote.
|
||
|
|
|
||
|
|
# git annex copy my_cool_big_file --to mys3
|
||
|
|
copy my_cool_big_file (to mys3...) ok
|
||
|
|
|
||
|
|
Once you've initialized a special remote in one repository, you can enable
|
||
|
|
use of the same special remote in other clones of the repository.
|
||
|
|
If the mys3 remote above was initialized on your laptop, you'll also want
|
||
|
|
to enable it on your desktop.
|
||
|
|
|
||
|
|
To do so, first get git-annex in sync (so it knows about
|
||
|
|
the special remote that was added in the other repository), and then
|
||
|
|
use `git annex enableremote`.
|
||
|
|
|
||
|
|
desktop# git annex sync
|
||
|
|
desktop# export AWS_ACCESS_KEY_ID="somethingotherthanthis"
|
||
|
|
desktop# export AWS_SECRET_ACCESS_KEY="s3kr1t"
|
||
|
|
desktop# git annex enableremote mys3
|
||
|
|
enableremote mys3 (checking bucket) ok
|
||
|
|
|
||
|
|
And now you can download files from the special remote:
|
||
|
|
|
||
|
|
desktop# git annex get my_cool_big_file --from mys3
|
||
|
|
get my_cool_big_file (from mys3...) ok
|
||
|
|
|
||
|
|
This has only scratched the surface of what can be done with
|
||
|
|
[[special_remotes]].
