![]() Special remotes are created with git annex initremote.Įvery remote has a unique name and UUID to manage data locations. Regular git remotes are set up with git annex init on the remote Options include S3, cloud drives, rsync, and many, many Git-annex special remotes, which essentially serve as key-value Regular git remotes work, if the git-annex shell tools are ![]() Remotes, git-annex remotes allow moving data around in a Provides a history (metadata) to other data files, keeps them safe,Īnd can be used like a normal repository.ĭata in one place isn’t enough, so let’s do more. So now, with little work, we have a normal git repository that Metadata helps us manage data much better once we get to level 3. Files canīe filtered and transferred based on this metadata. When files are first added, such as the date of addition). Structured metadata (arbitrary key/value pairs) can be assigned to anyįiles with git annex metadata (and can be automatically generated ![]() Stored in the primary git history itself. Hash HHHHH a unique hash of the file contents). Of git add, you can set which files should always be committed toĪt this point, git push|pull will only move metadata around (theĬommit message and link to. The largefiles settings will determine the behavior Original content is saved until you clean it up (unless you configure Run git annex unlock, and then commit it again when done. git/annex/objects and it is almost impossible for you toĪccidentally lose the data. Now, your content is safe: it is a symlink to somewhere in $ git commit # metadata: commit message, author, etc. You see that the smallįile is just there, but the large file is a symlink to. Using git annex get, one can get the raw data from another repoįor example, this is a ls -l of a real git repository which has a So, allĬlones know about all files, but don’t necessarily have all data. That and the metadata is distributed using regular git. Git-annex, the raw data is a separate storage area, and only links to You probably know what git is - it tracks versions of files. The biggest problems are that it can do everything, which makesĭocumentation quite dense, and the documentation is not that great. (commands such as git annex wanted, git annex numcopies, Git-annex is very focused on never losing data, it canĮnsure that one locked copy is always present in some repository. Is also on the cluster, and user environments have whatever is On all data is always stored in your object storage, all active data Well: you can define what content should be in each location andĭata is automatically distributed. You have more than two (or even more than one) repository, keeping Level 3: Manage synchronization across many repositories: Once You can put any file anywhere and metadata is You can easily do this git annex get, git annenx copy. Is shared, you might want to move the content between repositories. ![]() Repositories: Once the metadata is tracked and the git repository Level 2: Transfer and synchronize file content between Modification of primary copies of the data. This, files can be very safely locked to prevent accidental Record who produced the data, the history, and the hash of theĬontent, even without recording the contents into git. Level 1: Track metadata in git and lock file contents local-only:Įven on a single computer, one can rigorously track data files to Related to data management, but that is also its weakness (it doesn’t In particular, it tries to break git-annex into This page describes only a very limited set of features of git-annexĪnd how to use them. Stored in git and contents distributed using other management commands. This may seem contradictory, but itīasically creates a key-value store for large files, whose metadata is Which allows you to manage large files with git, without checking Video intro to git-annex, from Research Software Hour. ![]()
