A system, comprising:

• a processing circuit;
• and
• persistent storage media,
• the processing circuit being configured to:
• receive a first write command, for a first logical address;
• perform a write to the persistent storage media at a first physical address, corresponding to the first logical address;
• receive a first bookmarking command, for the first logical address;
• copy, in response to the first bookmarking command, an entry from a logical-to-physical table to a bookmark table, the entry corresponding to the first logical address;
• receive a second write command, for the first logical address;
• perform a write to the persistent storage media at a second physical address, corresponding to the first logical address;
• receive a first rewind command, for the first logical address;
• receive a read command, for the first logical address;
• and
• retrieve, in response to the read command, data from the first physical address.
