Abstract
Computer implemented methods for selective data deduplication in a multitenant environment are disclosed. Data deduplication of blocks written to a storage area associated with a tenant and redundant copies of the blocks written to other storage areas of other tenants is permitted or prevented based on tagging the first storage area associated with the tenant with a particular type of parameter. Responsive to detecting a write operation directed to the storage area tagged with a parameter indicating that deduplication is not permitted, a block to be written to the storage area is modified prior to hashing the block. Responsive to detecting a write operation directed to the storage area tagged with a parameter indicating that deduplication is permitted, a block to be written to the storage area is prevented from being modified prior to hashing the block.
