A computing device for rolling back a computing environment, the computing device comprising: one or more processors configured to: acquire a stream comprising entries including snapshot entries, memory entries, and input/output entries (420, 421), wherein each entry of the entries includes information and is associated with a timestamp, snapshot entries comprise processor state information to return an execution state of a processor to a specific point during prior execution of a process, memory entries include a first update to a memory location after a snapshot, but subsequent updates to the same memory location are not included in the stream until after an additional snapshot, input/output entries (420, 421) contain information necessary to recreate an input/output transaction, and one or more of the snapshot entries and the memory entries includes a reference to a previous snapshot entry and/or a previous memory entry to create a linked list of entries between the one or more of the snapshot entries and the memory entries and the previous snapshot entry and/or the previous memory entry; receive a snapshot entry of the snapshot entries, wherein the received snapshot entry is associated with a first timestamp; revert to a memory state by following references in the snapshot entries and/or memory entries back to that memory entry which follows the received snapshot entry; and re-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 using information for input/output operations corresponding to the input/output entries (420B, 421, 420C) associated with timestamps after the first timestamp. one or more processors configured to: acquire a stream comprising entries including snapshot entries, memory entries, and input/output entries (420, 421), wherein each entry of the entries includes information and is associated with a timestamp, snapshot entries comprise processor state information to return an execution state of a processor to a specific point during prior execution of a process, memory entries include a first update to a memory location after a snapshot, but subsequent updates to the same memory location are not included in the stream until after an additional snapshot, input/output entries (420, 421) contain information necessary to recreate an input/output transaction, and one or more of the snapshot entries and the memory entries includes a reference to a previous snapshot entry and/or a previous memory entry to create a linked list of entries between the one or more of the snapshot entries and the memory entries and the previous snapshot entry and/or the previous memory entry;
