Systems and methods for continuous data protection

A non-transitory, machine-readable medium storing instructions which, when read by a machine, cause the machine to perform operations in a method for continuous data protection for a virtual machine (VM) having a virtual disk, the operations comprising, at least:

• obtaining or identifying recoverable ranges of the VM;
• and
• recovering the VM from a most recent continuous point-in-time version of the virtual disk or a specific continuous point-in-time version of the virtual disk by implementing a set of algorithms, the set of algorithms to determine if a log chain in a series of log chains stored at a recovery site is valid for recovery of the VM, wherein a first algorithm of the set of algorithms includes determining a shortest log chain having a valid base snapshot, and a second algorithm in the set of algorithms includes determining a longest log chain having a valid base snapshot.
