While that may seem paradoxical, it is useful when dealing with files. Additionally, local copies of large files can be removed to free some space. Of course, they can be retrieved on request. git annex copy failed on the first time, but the second time it ended ok. git-annex allows managing files with git, without checking the file contents into git. What is git-annex Simply put, git-annex is an extension of git that provides some extra functionalities: Large files in the repository are not locally copied, when cloning or fetching/pulling. I ran it by hand and it worked, then I continued to copy-paste the commands from test.sh. First, one of the initremote commands failed this way. When I run test.sh, various commands fail with the message external special remote protocol error, unexpectedly received "" (unable to parse command)). I set the B2_* environment variables as required. git annex initremote cloud typeS3 encryptionnone port80 bucketjterrace-git-annex: initremote cloud (checking bucket.) (creating bucket in US.) ok (Recording state in git.) Create a test file and add it to git annex echo ' test ' > testfile.txt git annex add testfile.txt : add testfile.txt (checksum. set up the repository, and make a checkout Ive created a repository for technical talk videos, which you can fork on Github. This doesnt prevent using git-annex with GitHub, it just means you have to set up some other centralized location for the large files. I built git-annex-remote-b2 with the go command given in the README, then I copied the executable to /usr/local/bin. GitHub does not currently let git-annex store the contents of large files there.

If you tell git-annex that this remote won't lose data randomly by setting this remote's trust level higher, then those checkpresentkey calls (which turn into ListFileNames calls on B2) should go away. Improving the financial cost of this remoteīy default, all remotes are semitrusted in git-annex. Optionally, you may pass prefix=something to have git-annex-remote-b2 prepend something/ to the keys it stores in B2. If you pass them as arguments to initremote, the credentials will be stored in the git-annex repository and thus will be available to all clones of it. ~/repo $ git annex initremote b2 type=external externaltype=b2 bucket=mydataī2 credentials may either be given as arguments to initremote ( accountid=XXXX appkey=XXXXXXXXXXXXXXXX) or as the environment variables $B2_APP_KEY and $B2_ACCOUNT_ID.
