How to Correctly Apply the Preserve Last Access Time (LAT) Option to FSAA Scans

Questions​

  • Why are scans of my NAS failing to open files or skipping them?
  • If we select the Last Access Time (LAT) Preservation option, can we avoid a situation in which our FSAA job has changed the time of the last access?
  • What other options must be configured in the FSAA Data Collector Wizard when choosing the LAT Preservation?

Answer​

Follow the recommendations below:

  • The Only return file types with these comma-separated values (without leading dots) option changes the LAT. Therefore, if you want to preserve it, unselect this option. To find this option, go to the FSAA Data Collector Wizard > Default Scoping Options step > File Properties (Folder Summary) tab.
  • It is impossible to preserve LAT on a directory. It can be enabled for files only.
  • LAT Preservation is only applicable to Windows File Servers. Enabling Preserve LAT on NAS and other file servers may cause unexpected results.
