Verifying snapshot integrity

A method comprising:

• storing a snapshot at a first computing system, the snapshot having a first data integrity value;
• storing a copy of the snapshot as a replicated snapshot comprising a plurality of portions at a second computing system, respective portions of the plurality of portions being stored at respective computing nodes of the second computing system, wherein a first portion of the plurality of portions is stored at a first computing node of the plurality of computing nodes and a second portion of the plurality of portions is stored at a second computing node, the first and second computing nodes being different computing nodes;
• detecting an event corresponding to verification of integrity of the replicated snapshot;
• determining, in response to the event, a second data integrity value corresponding to the replicated snapshot based on the plurality of portions of the replicated snapshot at the second computing system;
• and
• determining, if the replicated snapshot can be assembled from the plurality of portions, based on at least whether data integrity value corresponds to the first data integrity value.

A system comprising:

• a storage medium having stored thereon a sequence of instructions;
• and
• one or more processors that execute the sequence of instructions to cause the one or more processors to perform a set of acts, the set of acts comprising,
• storing a snapshot at a first computing system, the snapshot having a first data integrity value;
• storing a copy of the snapshot as a replicated snapshot comprising a plurality of portions at a second computing system, respective portions of the plurality of portions being stored at respective computing nodes of the second computing system, wherein a first portion of the plurality of portions is stored at a first computing node of the plurality of computing nodes and a second portion of the plurality of portions is stored at a second computing node, the first and second computing nodes being different computing nodes;
• detecting an event corresponding to verification of integrity of the replicated snapshot;
• determining, in response to the event, a second data integrity value corresponding to the replicated snapshot based on the plurality of portions of the replicated snapshot at the second computing system;
• and
• determining, if the replicated snapshot can be assembled from the plurality of portions, based on at least whether the second data integrity value corresponds to the first data integrity value.
