Claim:
A method of managing data that is stored in a storage system, the method comprising: identifying, within a storage system, a first disruption region; identifying, within the storage system, a second disruption region that is separate from the first disruption region; associating portions of the first disruption region with portions of the second disruption region, where a first portion of the first disruption region is associated with a first portion of the second disruption region and a second portion of the first disruption region is associated with a second portion of the second disruption region; receiving a first update to be written to the storage system; and based on receipt of the first update to be written to the storage system: writing the first update to the second portion of the second disruption region; disabling read access to the first portion of the second disruption region during a first time period associated with writing the first update to the second portion to the second disruption region; enabling data to be read from the first portion of the first disruption region during the first time period associated with writing the first update to the second portion to the second disruption region; writing the first update to the second portion of the first disruption region; disabling read access to the first portion of the first disruption region during a second time period associated with writing the first update to the second portion to the first disruption region; and enabling data to be read from the first portion of the second disruption region during the second time period associated with writing the first update to the second portion to the first disruption region.
