質問 # 26
An administrator wants to back up a large file system with millions of files using either the NetBackup Accelerator feature or the NetBackup FlashBackup feature.
Which consideration is irrelevant when determining which feature to be used?

正解：D

解説：
The irrelevant consideration is the file system folder depth. When selecting between NetBackup Accelerator and NetBackup FlashBackup for a file system containing millions of files, the key design factors are capacity, file-count/metadata handling, change processing, policy support, and file system/platform compatibility-not how deeply folders are nested. Cohesity documents that Accelerator performs an initial full backup and creates a track log, then identifies changed data by comparing track-log information against file-system information for each file; on NTFS/ReFS it can also use the Windows change journal. Cohesity also states that Accelerator track-log sizing is relative to file system size and number of backup files, with sizing formulas based on number of files and used disk space-not directory depth. FlashBackup is documented as combining raw-partition backup speed with individual file restore, and the FlashBackup/FlashBackup- Windows policy types are platform-specific, making the type of file system/client platform relevant. Storage capacity is also relevant because FlashBackup size reporting uses the mounted Windows disk volume or UNIX raw disk partition size. References/topics: Accelerator operation, track-log sizing, FlashBackup policy types, and large file-system backup planning.
