Immutable storage support -
说明
Immutable storage or object is one that it can't be changed or modified after it has been created or until the retention period has passed. This provides an additional layer of protection against ransomware attacks. -
原因
Due to the increasing amount of ransomware attacks, cloud providers such as Amazon AWS and Microsoft Azure have implemented the immutable storage feature in order to have another layer of security. -
解决办法
Rapid Recovery 6.9 and newer supports object locking (immutability) for Amazon AWS S3, this applies to one-time and schedule archives.

Immutable storage is not fully supported in Rapid Recovery for Google Cloud and Microsoft Azure, however, here is how Rapid Recovery one-time and schedule archive behave with Google Cloud and Microsoft Azure.
One-time archivesGoogle Cloud: the task fails at the end with the following error message
Exception chain:
- An invalid request URL was provided. The request URL must either be an absolute URL or BaseAddress must be set.
- One or more errors occurred.
Microsoft Azure: It works.
Scheduled archives
do not work with immutable storage due to the nature of how the archive to immutable storage works.
Scheduled archives will work the first archive in Microsoft Azure, but the subsequent archive won't work this is because when a scheduled archive runs the 2nd time and onwards it requires deleting a file (backup.end) from the last archive folder created and creating the file (backup.end) into a new folder that will be created.
If you try a scheduled archive you will see an error similar to the following:
ErrorThe remote server returned an error: (409) Conflict.
- The remote server returned an error: (409) Conflict.
- Failed to delete file 'SQL2019\AABackup\7bfd8661-349b-4185-a444-24ea117efc12\backup.end' from 'immutablearchive'.
- One or more errors occurred.
