Repository groups
|
||
|
|
<p>
|
||
|
|
Each repository you configure git-annex to use is a member of a #
|
||
|
|
repository group. Each group of repositories has a different #
|
||
|
|
purpose.
|
||
|
|
<p>
|
||
|
|
Let's start with the <b>client repositories</b>. These are the #
|
||
|
|
repositories that contain files that you can directly use. Generally #
|
||
|
|
you'll have one client repository per computer. The whole point of #
|
||
|
|
the git-annex assistant is to keep these repositories in sync as you #
|
||
|
|
change files, add files, delete files, etc.
|
||
|
|
<p>
|
||
|
|
The next most important repository group is the #
|
||
|
|
<b>transfer repositories</b>. #
|
||
|
|
These are used to transfer files between clients, when the clients #
|
||
|
|
cannot directly talk to one-another. Transfer repositories only #
|
||
|
|
hold the files that need to be synced to other repositories, so they #
|
||
|
|
are relatively small.
|
||
|
|
<p>
|
||
|
|
You can get along without any <b>full backup repositories</b>, but #
|
||
|
|
they're a useful safeguard. These repositories accumulate every file
|
||
|
|
they can get ahold of. A large removable drive makes a good full backup #
|
||
|
|
repository.
|
||
|
|
<p>
|
||
|
|
Similarly, the <b>incremental backup repositories</b> try to back up #
|
||
|
|
every file, but these only accumulate files that are not already #
|
||
|
|
present in a full or incremental backup.
|
||
|
|
<p>
|
||
|
|
Next we come to the <b>archive repositories</b>.
|
||
|
|
The archive repositories coordinate together, so that each file is #
|
||
|
|
archived in only one place. When you move files into a folder named #
|
||
|
|
"archive", they'll be moved to an archive repository, and removed from #
|
||
|
|
all your client repositories. This is handy if you have old files #
|
||
|
|
you don't need anymore, but want to keep archived for later. #
|
||
|
|
When you copy or move a file out of an "archive" folder, it'll be #
|
||
|
|
retrieved from the archive repository.
|
||
|
|
<p>
|
||
|
|
The <b>small archive repositories</b> are like other archive #
|
||
|
|
repositories, but smaller. While archive repositories normally accumulate #
|
||
|
|
every file they can, small archive repositories only accumulate files #
|
||
|
|
once you put them in an "archive" directory.
|
||
|
|
<p>
|
||
|
|
Sometimes useful for devices like cameras are the #
|
||
|
|
<b>source repositories</b>. Repositories in this group only retain #
|
||
|
|
files until they can be moved to some other repository, like a client #
|
||
|
|
or transfer repository.
|
||
|
|
<p>
|
||
|
|
If you configure a repository that can be viewed by the public, #
|
||
|
|
but you don't want all your files to show up there, you can #
|
||
|
|
configure it to be a <b>public repository</b>. Then only files #
|
||
|
|
located in a directory you choose will be sent to it.
|
||
|
|
<p>
|
||
|
|
Finally, repositories can be configured to be in <b>manual mode</b>. This #
|
||
|
|
prevents content being automatically synced to the repository, but #
|
||
|
|
you can use command-line tools like `git annex get` and `git annex drop` #
|
||
|
|
to control what content is present.
