How to obtain, manage, and share code and data using VCS How git-annex and DataLad build atop git Warm-up with a typical git/github workflow This is particularly important if you're under the free trial limits of B2.# Using version control for code and data This means that the remote should be checked to see if it actually has data when doing an operation that assumes that the data is safe if they have it and unsafe if not (for example, a local git annex drop.) 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.
