Dynamically enabling/disabling change tracking on running replication for a multi-client file system

A non-transitory computer-readable medium storing computer-executable instructions that, when executed by one or more processors of a computing system, cause the one or more processors to perform operations comprising:

• creating, by a computing system, a first data structure storing change-tracking information used by one or more replications performed by a file system;
• controlling, by a first sub-system of the computing system, a first change-tracking mode for tracking changes made to a first set of snapshots in a file system;
• controlling, by a second sub-system of the computing system, a second change-tracking mode for tracking changes made to a second set of snapshots in the file system, the first change-tracking mode and the second change-tracking mode configured to effectuate storing change-tracking information in the first data structure;
• identifying, by the computing system, a common snapshot generation time between the first set of snapshots and the second set of snapshots, the common snapshot generation time being a particular snapshot generation time in which both the first change-tracking mode and the second change-tracking mode are in a same mode;
• and
• creating, by the computing system, a central change-tracking record comprising a common change-tracking mode field and a common snapshot generation time field, wherein identifying the common snapshot generation time comprises:
• verifying, by the computing system, that the first sub-system and the second sub-system have reached the common snapshot generation time.
