Abstract

Improved restore services in data storage environments are provided. In one example, a method includes the following steps. Generation of a point-in-time copy of a set of files associated with a data storage system is requested. The point-in-time copy is useable for restoring data blocks of the set of files onto the data storage system. The point-in-time copy of the set of files is generated at a data protection system operatively coupled to the data storage system in response to the requesting step. The point-in-time copy of the set of files is stored at the data protection system.

Claims (49)

1. A method comprising:

requesting generation of a point-in-time copy of a set of files associated with a data storage system, wherein the point-in-time copy is useable for restoring data blocks of the set of files onto the data storage system;

storing, at the data protection system, the point-in-time copy of the set of files;

restoring data blocks associated with the set of files onto the data storage system from the point-in-time copy stored on the data protection system; and

prior to the restoring step, determining whether to restore the entire set of files or a portion of the set of files;

wherein the restoring step further comprises accessing a file system filter at the operating system of the data storage system to enable the data protection system to determine which data blocks stored thereon correspond to the set of files to be restored;

wherein the file system filter is further configured to receive at least one request to recover the point-in-time copy of the set of files and to cooperate with a restore service generator of the data protection system to restore the data blocks associated with the set of files on the data storage system;

wherein the entire of the set of files includes one or more operating system files and one or more data files such that the one or more operating system files and the one or more data files are restored onto the data storage system in accordance with the requesting step; and

wherein the requesting, generating, storing, and restoring steps are implemented by one or more processing devices each comprising a processor coupled to a memory.

2. The method of claim 1 , wherein the file system filter maintains a placeholder file to provide access from the data storage system to data blocks of the set of files stored at the data protection system.

3. The method of claim 1 , wherein the data storage system comprises a block device storage system and the data protection system comprises a block device protection system.

4. The method of claim 1 , wherein the data protection system comprises one of a replication system and a backup system.

5. A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by one or more processing devices causes the one or more processing devices to:

request generation of a point-in-time copy of a set of files associated with a data storage system, wherein the point-in-time copy is useable for restoring data blocks of the set of files onto the data storage system;

generate, at a data protection system operatively coupled to the data storage system, the point-in-time copy of the set of files, in response to the requesting step;

store, at the data protection system, the point-in-time copy of the set of files;

restore data blocks associated with the set of files onto the data storage system from the point-in-time copy stored on the data protection system by accessing a file system filter at the operating system of the data storage system to enable the data protection system to determine which data blocks stored thereon correspond to the set of files to be restored; and

prior to restore, determine whether to restore the entire set of files or a portion of the set of files;

wherein the file system filter is further configured to receive at least one request to recover the point-in-time copy of the set of files and to cooperate with a restore service generator of the data protection system to restore the data blocks associated with the set of files on the data storage system; and

wherein the entire of the set of files includes one or more operating system files and one or more data files such that the one or more operating system files and the one or more data files are restored onto the data storage system in accordance with the request to generate.

6. An apparatus comprising:

one or more processing devices configured to:

request generation of a point-in-time copy of a set of files associated with a data storage system, wherein the point-in-time copy is useable for restoring data blocks of the set of files onto the data storage system;

generate, at a data protection system operatively coupled to the data storage system, the point-in-time copy of the set of files, in response to the requesting step;

store, at the data protection system, the point-in-time copy of the set of files;

restore data blocks associated with the set of files onto the data storage system from the point-in-time copy stored on the data protection system;

access a file system filter at the operating system of the data storage system to enable the data protection system to determine which data blocks stored thereon correspond to the set of files to be restored; and

prior to restore, determine whether to restore the entire set of files or a portion of the set of files;

wherein the file system filter is further configured to receive at least one request to recover the point-in-time copy of the set of files and to cooperate with a restore service generator of the data protection system to restore the data blocks associated with the set of files on the data storage system; and

wherein the entire of the set of files includes one or more operating system files and one or more data files such that the one or more operating system files and the one or more data files are restored onto the data storage system in accordance with the request of generation of the point-in-time copy.

7. The apparatus of claim 6 , wherein the file system filter maintains a placeholder file to provide access from the data storage system to data blocks of the set of files stored at the data protection system.

8. The apparatus of claim 6 , wherein the data protection system comprises one of a replication system and a backup system.

9. The method of claim 1 , wherein with respect to the data protection system and the data storage system, the point-in-time copy of the set of files are stored only on the data protection system.
