Smart data offload sync replication

A computing system, comprising:

• a memory;
• and
• at least one processor that is operatively coupled to the memory, the at least one processor being configured to perform the operations of:
• receiving, from a host device, a request to create a token that represents one or more data items that are stored in a first volume, the first volume being stored in a source system;
• estimating an I/O latency limit for the first volume;
• estimating a token creation time for the token;
• comparing the token creation time to the I/O latency limit;
• when the token creation time matches the I/O latency limit:
• creating the token, creating a snapshot pair, mapping the token to the snapshot pair, and returning the token to the host device, the snapshot pair including a first snapshot of the first volume that is created at the source system and a second snapshot of a replica of the first volume that is stored at a target system;
• when the token creation time does not match the I/O latency limit:
• creating the token, creating a first snapshot of the first volume at the source system, mapping the first snapshot to the token, and returning the token to the host device.

A non-transitory computer-readable medium storing one or more processor-executable instructions, which, when executed by at least one processor, cause the at least one processor to perform the operations of:

• receiving, from a host device, a request to create a token that represents one or more data items that are stored in a first volume, the first volume being stored in a source system;
• estimating an I/O latency limit for the first volume;
• estimating a token creation time for the token;
• comparing the token creation time to the I/O latency limit;
• when the token creation time matches the I/O latency limit:
• creating the token, creating a snapshot pair, mapping the token to the snapshot pair, and returning the token to the host device, the snapshot pair including a first snapshot of the first volume that is created at the source system and a second snapshot of a replica of the first volume that is stored at a target system;
• when the token creation time does not match the I/O latency limit:
• creating the token, creating a first snapshot of the first volume at the source system, mapping the first snapshot to the token, and returning the token to the host device.
