Import/Export Cache Data

NCache provides users with the ability to backup cache data for later use. To create the backup use the Export-CacheData PowerShell tool. Once data is exported, you can get all the items present in the existing backup of the cache along with the relevant Lucene documents using the Import-CacheData PowerShell tool. It is important to note that, you can only restore data for a distributed cache using the Import and Export cache data tools together. This is also helpful when you are updating the NCache version and want to restore the cached data for later use.

Important

The cache name must be the same while using Export-CacheData and Import-CacheData tools.
