Selective data deduplication in a multitenant environment

A computer-implemented method for selective data deduplication in a multitenant environment, comprising:

• permitting data deduplication of blocks written to a first storage area associated with a first tenant and redundant copies of the blocks written to other storage areas associated with other tenants based, at least in part, on tagging a first storage area associated with the first tenant with a first parameter;
• and
• responsive to detecting a write operation directed to the first storage area tagged with the first parameter:
• preventing modification of a block to be written to the first storage area prior to hashing the block.

A computer program product for selective data deduplication in a multitenant environment, the computer program product including one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions including instructions to:

• prevent data deduplication of blocks written to a first storage area associated with a first tenant and redundant copies of the blocks written to other storage areas associated with other tenants based, at least in part, on tagging the first storage area associated with the first tenant with a first parameter;
• and
• responsive to detecting a write operation directed to the first storage area tagged with the first parameter:
• modify a block to be written to the first storage area prior to hashing the block.

A computer system for selective data deduplication in a multitenant environment, comprising:

• one or more computer processors;
• one or more computer readable storage media;
• and
• computer program instructions, the computer program instructions being stored on the one or more computer readable storage media for execution by the one or more computer processors, and the computer program instructions including instructions to:
• prevent data deduplication of blocks written to a first storage area associated with a first tenant and redundant copies of the blocks written to other storage areas associated with other tenants based, at least in part, on tagging the first storage area associated with the first tenant with a first parameter;
• and
• responsive to detecting a write operation directed to the first storage area tagged with the first parameter:
• modify a block to be written to the first storage area prior to hashing the block.
