Dell NetWorker 19.9 Administration Guide

File type devices

File type devices (FTDs) are legacy devices and their use is limited. Continued support for legacy and test purposes is maintained, however you are encouraged to use AFTD or DD Boost devices in preference to FTD. An FTD can be configured on the NetWorker server by creating a new Device resource in the same manner as for other storage devices.

The following conditions and restrictions apply to FTDs:

• The upper limit of save set size on an FTD may be either:
  • The upper limits supported by the operating system
  • The file size specified by the disk device vendor
• If multiple FTDs are configured on a system, each device must have a unique name.
• To use multiple FTDs on the same disk, partition the disk and create only one FTD per partition.
• Dynamic Drive Sharing is not supported.
• For FTDs created on a UNIX or Linux network file system (NFS):
  • The file system used for the FTD must not be used for any other data.
  • There must be one FTD per NFS system.
  • The Volume Default Capacity attribute for the FTD must be set to a size that is less than 100 percent of the total capacity of the file system.
    NOTE:Data loss will result if a full FTD is made appendable while a backup is pending completion and a save set is partially written to the full FTD. In this case, the partial save set (currently in “incomplete” state) will be overwritten.
