Enhancement: Support B2 API keys restricted to hiding but not deleting files
|
|
|
|
When the B2 backend does not have the necessary permissions to permanently
|
|
delete files, it now automatically falls back to hiding files. This allows
|
|
using restic with an application key which is not allowed to delete files.
|
|
This can prevent an attacker from deleting backups with such an API key.
|
|
|
|
To use this feature create an application key without the `deleteFiles`
|
|
capability. It is recommended to restrict the key to just one bucket.
|
|
For example using the `b2` command line tool:
|
|
|
|
`b2 create-key --bucket <bucketName> <keyName> listBuckets,readFiles,writeFiles,listFiles`
|
|
|
|
Alternatively, you can use the S3 backend to access B2, as described
|
|
in the documentation. In this mode, files are also only hidden instead
|
|
of being deleted permanently.
