Zimbra NG HSM Utilities

Item Deduplication

  • Save precious disk space by deduplicating items in your Zimbra volumes.

Advanced Volume Operations

  • Obtain full control of your Zimbra volumes through the Zimbra NG HSM CLI.

Module integration

When starting an import or a restore with Zimbra NG Backup the "Apply HSM Policy" option is available.

Enabling this option will force Zimbra NG HSM to apply the HSM policy for each mailbox Zimbra NG Backup is done restoring, so while the restore itself will be completely done on the primary store, as soon as a mailbox is completely restored the proper data will be moved to the secondary store.

Best Practices

  • Zimbra official guidelines for Filesystem Performance Tuning apply to Zimbra NG HSM too: Zimbra Performance Guidelines Filesystem
  • We strongly advice against the use of network shares (or any high access latency solution) as your Zimbra primary store volume.
