Abstract
Techniques to exclude files from backup are disclosed. In various embodiments, a database that includes an exclude set table configured to store data associated with one or more files identified to be excluded from backup is accessed. Data retrieved from the database is used to exclude one or more of said one or more files from a backup. In some embodiments, files are excluded from the backup at least in part by deleting the files from a shadow copy volume created in connection with said backup.
Claims18
A computer-implemented method of excluding files from backup, comprising:
- accessing, by one or more processors, a database that that stores data associated with one or more files identified to be excluded from backup in connection with an incremental backup;
- and
- using, by the one or more processors, at least the data stored in the database for one or more files excluded from a previous backup to exclude one or more of the one or more files from the incremental backup, comprising:
- locating the one or more files identified to be excluded from the incremental backup;
- and
- ensuring that data blocks associated with the located one or more files excluded from the previous backup are excluded from the incremental backup.
A system to exclude files from backup, comprising:
- a data storage device configured to store a database that includes data associated with one or more files identified to be excluded from backup in connection with an incremental backup;
- and
- a processor coupled to the data storage device and configured to use at least the data stored in the database for one or more files excluded from a previous backup to exclude one or is more of the one or more files from the incremental backup, comprising locating the one or more files identified to be excluded from the incremental backup, and ensuring that data blocks associated with the located one or more files excluded from the previous backup are excluded from the incremental backup.
A computer program product embodied in a tangible, non-transitory computer readable storage medium, comprising computer instructions for:
- accessing, by one or more processors, a database that that stores data associated with one or more files identified to be excluded from backup in connection with an incremental backup;
- and
- using, by the one or more processors, at least the data stored in the database for one or more files excluded from a previous backup to exclude one or more of the one or more files from the incremental backup, comprising:
- locating the one or more files identified to be excluded from the incremental backup;
- and
- ensuring that data blocks associated with the located one or more files excluded from the previous backup are excluded from the incremental backup.
