Troubleshooting and Help
Before calling Quantum Support, review these FAQs:
Question:
How can I free up disk space on my DXi?
Answer:
There are multiple ways you can remove data from your DXi:
• You can delete data from your NAS share.
• If the DXi is a target system, you can delete the replicated snapshots.
• After one or more of the previous actions have been taken, you must run space
reclamation to free up the space.
Question:
When should I schedule replication and space reclamation for best performance?
Answer:
If possible, try to schedule your backups, replication and space reclamation to run
at different times throughout the day. By keeping those processes separate your
blockpool performance will improve.
Question:
How can I increase my deduplication rate?
Answer:
Three things that will hurt your deduplication ratio are software compression,
encryption, and multiplexing. Most backup applications have options that can be
enabled or disabled for these functions and are often enabled by default. They should
be disabled or the DXi will not be able to achieve an optimal deduplication ratio.
Question:
What should I do when my backups fail?
Answer:
Backup jobs may have failed for some of the following reasons:
• The DXi ran out of space during the backup window.
• Your backup host lost network connectivity to the DXi.
• Your backup application may have crashed. Try re-running the backup before
contacting Quantum support.
