Enhancement: Add support for non-global Azure clouds
|
||||
|
||||
Restic backups on azure only worked for storages on the global domain `core.windows.net`. This meant that backups to other domains such as Azure China (`core.chinacloudapi.cn') were not supported. Restic now allows overriding the global domain using the environment variable `AZURE_ENDPOINT_SUFFIX'.

Restic will use Azure's global domain ``core.windows.net`` by default. You can specify other

Afterwards you can initialize a repository in a container called ``foo`` in the

root path like this:
