Storage tier selection for replication and recovery

A non-transitory computer-readable storage medium storing program instructions executable to:

• receive a replication stream at a source replication appliance, wherein
• the source replication appliance is configured to replicate data to a storage tier of a plurality of storage tiers, and
• each storage tier of the plurality of storage tiers differs from at least one other of the plurality of storage tiers in at least one storage characteristic of a plurality of storage characteristics;
• identify one or more portions of the replication stream based on one or more input/output (I/O) characteristics of the one or more portions of the replication stream;
• and
• transmit a command to store at least one portion of the one or more portions in one of the plurality of storage tiers other than the storage tier, wherein
• the at least one portion of the one or more portions is to be stored in the one of the plurality of storage tiers based, at least in part, on the one or more I/O characteristics of the at least one portion, storage type information, and a storage cost associated with the each storage tier of the plurality of storage tiers,
• the storage cost associated with the each storage tier is based on one or more storage characteristics of the plurality of storage characteristics of the each storage tier, and
• the storage type information indicates that at least one of the plurality of storage tiers is implemented on a block storage device of one or more block storage device and at least another of the plurality of storage tiers is implemented on an object storage device of one or more object storage devices.

A system comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors, wherein the memory stores program instructions executable by the one or more processors to:
• receive a replication stream at a source replication appliance, wherein
• the source replication appliance is configured to replicate data to a storage tier of a plurality of storage tiers, and
• each storage tier of the plurality of storage tiers differs from at least one other of the plurality of storage tiers in at least one storage characteristic of a plurality of storage characteristics;
• identify one or more portions of the replication stream based on one or more input/output (I/O) characteristics of the one or more portions of the replication stream;
• and
• transmit a command to store at least one portion of the one or more portions in one of the plurality of storage tiers other than the storage tier, wherein
• the at least one portion of the one or more portions is to be stored in the one of the plurality of storage tiers based, at least in part, on the one or more I/O characteristics of the at least one portion, storage type information, and a storage cost associated with the each storage tier of the plurality of storage tiers,
• the storage cost associated with the each storage tier is based on one or more storage characteristics of the plurality of storage characteristics of the each storage tier, and
• the storage type information indicates that at least one of the plurality of storage tiers is implemented on a block storage device of one or more block storage device and at least another of the plurality of storage tiers is implemented on an object storage device of one or more object storage devices.
