Abstract
A mechanism is provided for reducing the backup time of data files from a memory. Data files are pre-staged by identifying the data files in the memory to be backed up to a backup storage system, sorting the data files by size thereby forming a set of small data files and a set of large data files, and copying the set of small data files to a cache while leaving the set of large data files in a disk subsystem. The set of small data files are then backed-up from the cache and the set of large data files are backed-up from the disk subsystem to a backup storage system. Thus, the time required to backup the set of small data files from the cache is performed at a faster rate as compared to backing up the set of large data files from the disk subsystem.

A method, in a data processing system, for reducing the backup time of data files from a memory, the method comprising:
- pre-staging, by a processor in the data processing system, the data files by:
- identifying, by the processor, the data files in the memory to be backed up to a backup storage system;
- sorting, by the processor, the data files by size, thereby forming a set of small data files and a set of large data files;
- and
- copying, by the processor, the set of small data files to a cache within the memory while leaving the set of large data files in a disk subsystem within the memory;
- and
- backing up, by the processor, the set of small data files from the cache and the set of large data files from the disk subsystem to a backup storage system, wherein a time required to backup the set of small data files from the cache is performed at a faster rate as compared to backing up the set of large data files from the disk subsystem due to a reduction in access time required to access each of the small data files.
