Live rollback for a computing environment

摘要

A first computing device is provided for rolling back a computing environment. The computing device includes processors configured to acquire a stream containing entries including snapshot entries, memory entries, and input/output entries wherein each entry includes information and is associated with a timestamp. The processors are further configured to receive a snapshot entry associated with a first timestamp, revert to a memory state using information provided in at least one memory entry associated with a timestamp after the first timestamp, and re-execute a previously executed process, wherein the re-execution of the process is started using the first timestamp, information from the received snapshot entry, and information for input/output operations corresponding to the input/output entries associated with timestamps after the first timestamp.

1. A first computing device for rolling back a computing environment, the first computing device comprising:
one or more processors configured to:
acquire a stream containing entries including snapshot entries, a plurality of memory entries, and at least one input/output entry, wherein:
each entry of the entries includes information and is associated with a timestamp; anda first memory entry of the plurality of memory entries includes a reference to a second memory entry of the plurality of memory entries;receive a snapshot entry of the snapshot entries, wherein the received snapshot entry is associated with a first timestamp;revert to a memory state using information provided in the plurality of memory entries and following the reference includes in the first memory entry to the second memory entry; andre-execute a previously executed process, wherein the re-execution of the process is started using the first timestamp and information from the received snapshot entry and includes information for input/output operations corresponding to the at least one input/output entry associated with timestamps after the first timestamp.
