Point in Time Blob Restore

A method of point in time blob restoration, comprising:

• receiving a request to restore a particular blob range to a particular point in time;
• blocking read and write operations on the particular blob range requested to be restored;
• determining which blobs in the particular blob range have changed since the particular point in time based, at least in part, upon information stored in at least one of a change log or a deleted blob store;
• determining whether the requested restore operation can be performed;
• and
• when it is determined that the requested restore operation can be performed, restoring at least one blob determined to have changed since the particular point in time based, at least in part, upon information stored in at least one of the change log or the deleted blob store.

A computer storage medium storing computer-readable instructions that when executed cause a computing device to:

• receive a request to restore a particular blob range to a particular point in time;
• block read and write operations on the particular blob range requested to be restored;
• determine which blobs in the particular blob range have changed since the particular point in time based, at least in part, upon information stored in at least one of a change log or a deleted blob store;
• determine whether the requested restore operation can be performed;
• and
• when it is determined that the requested restore operation can be performed, restore at least one blob determined to have changed since the particular point in time based, at least in part, upon information stored in at least one of the change log or the deleted blob store.
