Monitoring deduplication storage capacity and usage
Several options exist to monitor your deduplication storage capacity and usage.
See “About deduplication capacity and usage reporting” on page 87.
See “About deduplication container files” on page 89.
See “Viewing capacity within deduplication container files” on page 89.
About deduplication capacity and usage reporting
Several factors may affect the expected usage results, as follows:
■ Expiredbackupsmay notchangethe availablesize andtheused size.Anexpired
backup may have no unique data segments. Therefore, the segments remain
valid for other backups.
■ NetBackup Deduplication Manager clean-up may not have run yet. The
Deduplication Manager performs clean up twice a day. Until it performs
clean-up, deleted image fragments remain on disk.
If you use operating system tools to examine storage space usage, their results
may not match the usage reported by NetBackup, as follows:
■ The operating system tools cannot report usage accurately. The storage
implementation uses container files. Deleted segments can leave free space
in container files, but the container file sizes do not change.
■ Ifotherapplications usethestorage, NetBackupcannotreport usageaccurately.
NetBackup requires exclusive use of the storage.
Table 6-3 describes the options for monitoring capacity and usage.
