Dell NetWorker 19.9 Administration Guide

AFTD operation verification

The AFTD can be deployed in varying environments with local disks, and with NFS-mounted or CIFS-mapped disks. The configuration of this feature affects its operation. Ensure that the AFTD is fully operational in the production environment before deploying it as part of regularly scheduled operations.

As part of the validation process, test these operations:

• Backup
• Recover
• Staging
• Cloning
• Maximum file size compatibility between the operating system and a disk device
• Use of a volume manager to increase the file system size while the file system is in use
• File system behavior when the disk is full

Some versions of NFS and CIFS drop data when a file system becomes full. Be sure to use versions of NFS, CIFS, and operating systems that fully support full file systems. On some disk devices, the volume labeling process can take longer than expected. Labeling time depends on the type of disk device used and does not indicate a limitation of the NetWorker software. The upper limits of save set size depend on either the upper limits supported by the operating system or the file size specified by the disk device’s vendor.
