Abstract

Various systems, methods, and processes for optimizing access to production data in application development and testing environments are disclosed. If an input/output (I/O) operation is a read operation, a storage location on a virtual storage unit at which the read operation is to be performed is determined. Also determined is whether an earlier write operation was performed at the storage location. If an earlier write operation was performed at the storage location, the read operation is performed on one or more virtual data files. However, if the earlier write operation was not performed at the storage location, the read operation is performed on allocated storage space.

Claims

1. A method comprising:

in response to determining that an input/output (I/O) operation is a write operation, performing the write operation on a virtual data file, wherein

the virtual data file is stored in a virtual disk,

the virtual disk is part of a virtual storage unit, and

the virtual data file is part of an allocated storage space; and

in response to determining that the I/O operation is a read operation,

determining a storage location on the virtual storage unit at which the read operation is to be performed,

determining whether an earlier write operation was performed at the storage location,

in response to determining that the earlier write operation was performed at the storage location, performing the read operation on the virtual data file, and

in response to determining that the earlier write operation was not performed at the storage location, performing the read operation on the allocated storage space.
