Cache size during restore

The size of the cache may need to increase when you restore large amounts of data from an Instant Recovery snapshot. For instance, if you restore an entire raw partition to a source device that has an active Instant Recovery snapshot, writing the restore data causes the active snapshot to cache all blocks from the raw partition that resides on the source device. A cache that was large enough when the snapshot was first initiated may no longer be large enough. The large restore multiplies the write-to-cache activity, increasing the space that is needed for cache.

Use the following copy-on-write snapshot methods with Instant Recovery only when small amounts of data (individual files) are likely to be restored:
