Restore of secondary data using thread pooling
First Claim
1. A system for restoring data from secondary storage to primary storage, the system comprising:
- a secondary storage controller computer comprising computer hardware and in communication with one or more secondary storage devices in a secondary storage subsystem, the secondary storage controller computer configured to;
receive a first instruction to obtain a first secondary copy of a first data set from the one or more secondary storage devices, the first instruction associated with a first restore operation in which the first data set is restored to one or more primary storage devices in a primary storage subsystem;
receive a second instruction to obtain a second secondary copy of a second data set from the one or more secondary storage devices, the second instruction associated with a second restore operation in which the second data set is restored to the one or more primary storage devices;
in response to the first instruction;
instantiate a first restore thread on a processor of the secondary storage controller computer;
using the first restore thread, retrieve the first secondary copy from the one or more secondary storage devices; and
forward the retrieved first secondary copy to the primary storage subsystem for storage on the one or more primary storage devices; and
in response to the second instruction;
using the first restore thread, retrieve the second secondary copy from the one or more secondary storage devices; and
forward the retrieved second secondary copy to the primary storage subsystem for storage on the one or more primary storage devices.

Abstract
A system according to certain aspects may include a secondary storage controller computer configured to: in response to a first instruction to obtain a first secondary copy of a first data set from a secondary storage device(s), the first instruction associated with a first restore operation: instantiate a first restore thread on a processor of the secondary storage controller computer; using the first restore thread, retrieve the first secondary copy from the secondary storage device(s); and forward the retrieved first secondary copy to a primary storage subsystem for storage; and in response to a second instruction to obtain a second secondary copy of a second data set from the secondary storage device(s), the second instruction associated with a second restore operation: using the first restore thread, retrieve the second secondary copy from the secondary storage device(s); and forward the retrieved second secondary copy to the primary storage subsystem for storage.

10. A method for restoring data from secondary storage to primary storage, the method comprising:
with a secondary storage controller computer comprising one or more processors and residing in a secondary storage subsystem, receiving a first instruction to obtain a first secondary copy of a first data set from one or more secondary storage devices residing in the secondary storage subsystem, the first instruction associated with a first restore operation in which the first data set is restored to one or more primary storage devices in a primary storage subsystem; receiving a second instruction to obtain a second secondary copy of a second data set from the one or more secondary storage devices, the second instruction associated with a second restore operation in which the second data set is restored to the one or more primary storage devices; in response to the first instruction; instantiating a first restore thread on a processor of the secondary storage controller; using the first restore thread, retrieving the first secondary copy from the one or more secondary storage devices; and forwarding the retrieved first secondary copy to the primary storage subsystem for storage on the one or more primary storage devices; and in response to the second instruction; using the first restore thread, retrieving the second secondary copy from the one or more secondary storage devices; and forwarding the retrieved second secondary copy to the primary storage subsystem for storage on the one or more primary storage devices. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
