Feature (What you would like to be added):

Users might wish to enable the bucket lock mechanism for their objects stored in buckets to use write-once-read-many(WORM) model. As the storage providers exhibit varying functionality for bucket lock, we need to adapt our approach based on each provider's specific bucket lock implementation.

To support the bucket lock mechanism, the following features of the backup-restore process need to be enhanced:

1. Garbage collection of backups.
2. The ability to skip certain snapshots during restoration, if required.

• AWS's S3
  • Add Bucket Lock immutable objects support for AWS S3 #818
• GCP's GCS
  • Add Bucket Lock immutable object support for Google Cloud Storage. #776
• Azure's ABS
  • Add Container level WORM immutable object support for Azure Blob Storage. #781
