Abstract
Embodiments for deleting encryption keys in a data storage system by storing a current encryption key in a key table, the current key encrypting at least some data in one or more data containers of a filesystem of the data storage system. A key table maintains a starting container ID and an ending container ID for each container encrypted by the current encryption key, and a deleted container count counting a number of containers of the one or more data containers deleted from the file system. The process determines if the number of containers in the deleted container count equals a number of containers having data encrypted by the encryption key as determined by the starting container ID and ending container ID, and if so, marks the key for deletion in a garbage collection operation, which then deletes the key from the key table.
