Abstract

A computer network for backing up data and program files located on networked workstations onto a centralized backup media of a backup device of the network. The backup computer network allows users of workstations of remote nodes to preselect files (by name and by file selection criteria) on their workstation which are to be backed onto the centralized backup media. The file selection processes are therefore distributed throughout the network which considerably increases the speed of backing up over the network.

Claims

1. A computer network comprising in combination:

a plurality of nodes including a controlling node and one or more remote nodes, said controlling node having computer means and a central backup device, at least one of said remote nodes having computer means and a local storage device;

means located on each of said remote nodes for creating a remote backup set containing a list of files located on respective said local storage devices to be transferred to said central backup device; and

means located on said controlling node for transferring said files listed on said remote nodes over the network to said central backup device.

2. The computer network as set forth in claim 1, wherein at least one of said remote nodes includes a plurality of said local storage devices and wherein said means for creating respective said remote backup sets comprises means for selecting one or more of said remote node'"'"'s local storage devices whose files are then to be used to create said list of files to be transferred to said central backup device.

3. The computer network as set forth in claim 1, wherein said means for creating respective said remote backup sets comprises means for allowing a selection of files to be included in said list of files to be transferred based upon predetermined selection criteria.

4. The computer network as set forth in claim 1, wherein said means for creating respective said remote backup sets comprises means for including files in said list of files which have changed since a previous backup thereby allowing incremental backups.

5. The computer network as set forth in claim 1, further including means located on said controlling mode for initiating said means for creating respective said remote backup sets, thereby allowing contemporaneous creation of respective said remote backup sets.

6. A method for transferring files from nodes of a computer network to a central backup device, the computer network having a plurality of nodes including a controlling node and one or more remote nodes, at least one remote node having computer means and one or more local storage devices, the method comprising the steps of:

creating a remote backup set on each remote node containing a list of files located on each remote node'"'"'s storage devices to be transferred to the central backup device; and

transferring the files listed on the remote backup set of each remote node over the network to the central backup device.

7. The method as set forth in claim 6, wherein at least one of the remote nodes includes a plurality of the local storage devices and wherein the step of creating a remote backup set comprises the step of selecting one or more of the remote node'"'"'s local storage devices whose files are then to be used to create the list of files to be transferred to the central backup device.

8. The method as set forth in claim 6, wherein the step of creating a remote backup set comprises the step allowing a selection of files to be included in the list of files to be transferred based upon predetermined selection criteria.

9. The method as set forth in claim 6, wherein said the step of creating a remote backup set comprises the step of including files in the list of files which have changed since a previous backup thereby allowing incremental backups.

10. The method as set forth in claim 6, further including the step of contemporaneously initiating said means for creating a remote backup set, thereby allowing contemporaneous creation of remote backup sets.
