Soft Delete- Azure Storage Blobs?
By using Azure Storage Blobs Soft Delete, we can easily
recover our data when it is erroneously modified or deleted by an application
or other storage account user.
How
soft delete works?
When enabled, soft delete enables you to save and recover
your data when blobs or blob snapshots are deleted. This protection extends to
blob data that is erased as the result of an overwrite.
When data is deleted, it transitions to a soft deleted
state instead of being permanently erased. When soft delete is on and you
overwrite data, a soft deleted snapshot is generated to save the state of the
overwritten data. Soft deleted objects are invisible unless explicitly listed.
You can configure the amount of time soft deleted data is recoverable before it
is permanently expired.
Soft delete is backwards compatible, so you don't have to
make any changes to your applications to take advantage of the protections this
feature affords.
Steps
to Enable and Disable Soft Delete:
When we create a new account, soft delete is off by default.
Open Storage Account -> Select Data Protection under Blob
Service. Here Do Enable Soft Delete.
