This invention relates to systems and methods for executing complex data protection operations.
Data is increasingly one of an organization's most valuable assets. Accordingly, it is paramount that an organization protect its data, particularly its business-critical data. Statistics show that a high percentage of organizations, as high as fifty percent, are unable to recover from an event of significant data loss, regardless of whether the loss is the result of a virus, data corruption, physical disaster, software or hardware failure, human error, or the like. At the very least, significant data loss can result in lost income, missed business opportunities, and/or substantial legal liability. Accordingly, it is important that an organization implement adequate policies and procedures to prevent such losses from occurring. In many cases, an organization will protect data using a variety of strategies such as traditional backups, remote data replication, and periodic snapshots. Each of these protection strategies has advantages and disadvantages and uses different techniques to restore lost or damaged data.
In some cases, an administrator may wish to utilize a variety of data protection strategies in a specified order and on a specified schedule. In certain cases, the data protection strategies and associated orders and schedules may be needed to satisfy a service-level-agreement (SLA) or provide desired life cycle management of data. In some cases, data protection strategies that are used may originate from different data protection products which in some cases have different vendors. In any event, selecting a desired set of data protection strategies and executing them in a desired order and on a desired schedule can be a time-consuming and laborious process for a system administrator.
In view of the foregoing, what are needed are systems and methods to execute complex data protection operations made up of multiple data protection functions. Ideally, such systems and methods will simplify the ordering and scheduling of the data protection functions.
The invention has been developed in response to the present state of the art and, in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available systems and methods. Accordingly, systems and methods are disclosed for executing complex data protection operations. The features and advantages of the invention will become more fully apparent from the following description and appended claims, or may be learned by practice of the invention as set forth hereinafter.
Consistent with the foregoing, a method for executing complex data protection operations is disclosed. In one embodiment, such a method includes generating multiple complex data protection operations, where each complex data protection operation includes multiple data protection functions pre-arranged in a specified order and on a specified schedule. The method further presents the multiple complex data protection operations to a user in the form of a menu. This menu includes multiple menu options, where each menu option is associated with one of the complex data protection operations. The method further enables the user to select a menu option, and executes the complex data protection operation associated with the menu option selected by the user.
A corresponding system and computer program product are also disclosed and claimed herein.
In order that the advantages of the invention will be readily understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through use of the accompanying drawings, in which:
It will be readily understood that the components of the present invention, as generally described and illustrated in the Figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the invention, as represented in the Figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of certain examples of presently contemplated embodiments in accordance with the invention. The presently described embodiments will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout.
The present invention may be embodied as a system, method, and/or computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium may be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages.
The computer readable program instructions may execute entirely on a user's computer, partly on a user's computer, as a stand-alone software package, partly on a user's computer and partly on a remote computer, or entirely on a remote computer or server. In the latter scenario, a remote computer may be connected to a user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, may be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

As shown, the network environment 100 includes one or more computers 102, 106 interconnected by a network 104. The network 104 may include, for example, a local-area-network (LAN) 104, a wide-area-network (WAN) 104, the Internet 104, an intranet 104, or the like. In certain embodiments, the computers 102, 106 may include both client computers 102 and server computers 106 (also referred to herein as “host systems” 106). In general, the client computers 102 initiate communication sessions, whereas the server computers 106 wait for requests from the client computers 102. In certain embodiments, the computers 102 and/or servers 106 may connect to one or more internal or external direct-attached storage systems 112 (e.g., arrays of hard-disk drives, solid-state drives, tape drives, etc.). These computers 102, 106 and direct-attached storage systems 112 may communicate using protocols such as ATA, SATA, SCSI, SAS, Fibre Channel, or the like. One or more of the storage systems 112 may be used in association with the systems and methods disclosed herein.
The network environment 100 may, in certain embodiments, include a storage network 108 behind the servers 106, such as a storage-area-network (SAN) 108 or a LAN 108 (e.g., when using network-attached storage). This network 108 may connect the servers 106 to one or more storage systems 110, such as arrays 110a of hard-disk drives or solid-state drives, tape libraries 110b, individual hard-disk drives 110c or solid-state drives 110c, tape drives 110d, CD-ROM libraries, or the like. To access a storage system 110, a host system 106 may communicate over physical connections from one or more ports on the host 106 to one or more ports on the storage system 110. A connection may be through a switch, fabric, direct connection, or the like. In certain embodiments, the servers 106 and storage systems 110 may communicate using a networking standard such as Fibre Channel (FC). One or more of the storage systems 110 may be used in association with the systems and methods disclosed herein.

In selected embodiments, the storage controller 200 includes one or more servers 206. The storage controller 200 may also include host adapters 208 and device adapters 210 to connect the storage controller 200 to host devices 106 and storage devices 204, respectively. Multiple servers 206a, 206b may provide redundancy to ensure that data is always available to connected hosts 106. Thus, when one server 206a fails, the other server 206b may pick up the I/O load of the failed server 206a to ensure that I/O is able to continue between the hosts 106 and the storage devices 204. This process may be referred to as a “failover.”
In selected embodiments, each server 206 may include one or more processors 212 and memory 214. The memory 214 may include volatile memory (e.g., RAM) as well as non-volatile memory (e.g., ROM, EPROM, EEPROM, hard disks, flash memory, etc.). The volatile and non-volatile memory may, in certain embodiments, store software modules that run on the processor(s) 212 and are used to access data in the storage devices 204. These software modules may manage all read and write requests to logical volumes in the storage devices 204.
One example of a storage system 110a having an architecture similar to that illustrated in

A point-in-time-copy data protection function may generate a point-in-time copy 302 of the primary data 300. This point-in-time copy 302 may reside on the same storage system 110a1 as the primary data 300 or be generated on a different storage system 110. In certain cases, a backup data protection function may back up data in the point-in-time copy 302 instead of the primary data 300 to reduce the I/O workload on the primary data 300 and/or ensure that the backup contains data associated with a certain point in time. For example, a backup data protection function may copy data in the point-in-time copy 302 to a backup storage system 110a3, such as a cloud-based backup storage system 110a3. This may create a backup copy 308 of the point-in-time copy 302. In this example, the backup data protection function relies on completion of the point-in-time copy 302 data protection function, thus requiring a specified order of completion.

Other settings are also possible. For example, a user interface (not shown) may enable an administrator to establish a retry policy to determine what to do in failure situations. For example, if a snapshot data protection function fails, the data protection function may be retried up to a certain number times. Similarly, if a snapshot data protection function succeeds but an associated backup function fails, the system may continue processing but issue a warning. Alternatively, if a snapshot data protection function succeeds but an associated backup function fails, the system may retry the complex data protection operation but fall back to a previous policy if the complex data protection operation fails. These represent just a few examples of retry policies. Other retry policies are possible and within the scope of the invention.
