Monitoring deduplication storage capacity and usage
To view and manage VxUL log files, you must use NetBackup log commands. For information about how to use and manage logs on NetBackup servers, see the NetBackup Troubleshooting Guide.
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:
■Expired backups may not change the available size and the used size. An expired backup may have no unique data segments. Therefore, the segments remain valid for other backups.
■NetBackup Deduplication Manager
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.
■If other applications use the storage, NetBackup cannot report usage accurately. NetBackup requires exclusive use of the storage.
