Claim 0:
1. A method performed by a storage node, the method comprising:
receiving by the storage node a restore request that requests restoration of a data object from a first storage tier to a second storage tier, the restore request including a first indication of an active time period for the data object to remain stored to the second storage tier;
setting a restore expiry timestamp, based on the active time period and a restore start timestamp, in response to a second indication that the first storage tier has accepted the restore request, wherein the restore start timestamp indicates a start time of the restoration of the data object to the second storage tier, and the restore expiry timestamp indicates an expiry time of the active time period for the data object remaining stored to the second storage tier;
determining a re-tier timestamp from a combination of the restore start timestamp and the restore expiry timestamp;
comparing a current timestamp to the re-tier timestamp to determine whether the active time period has elapsed;
responsive to determining that the active time period has not elapsed, repeating a scan of metadata associated with a plurality of data objects including the data object and the comparing; and
responsive to determining that the active time period has elapsed, requesting a cloud endpoint to move the data object from the second storage tier to the first storage tier.
