We are getting ready to deploy Hitachi's HCP archiver which basically archives data on our NAS that hasn't been accessed in a certain amount of time. It does this by moving the blocks to lower-tier storage and placing a stub file in its place on the NAS. Any subsequent reads of that stub file will result in the file being "unarchived" (this is all transparent to the client and happens on the back end). So to prevent netbackup from causing files to be "unarchived" during backups we will need to deploy the following NDMP settings:
NDMP_BLUEARC_EXCLUDE_MIGRATED = Y NDMP_BLUEARC_EXTERNAL_LINKS = recreate_link My question is, does anyone know the impact these settings will have on NDMP overhead/performance? We have multiple 12TB volumes with large numbers of files and I'm concerned this will become even more of an issue. It's gotta add some kind of overhead, I'm just concerned on how much. +---------------------------------------------------------------------- |This was sent by chuck.car...@gmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +---------------------------------------------------------------------- _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
