Blue Iris backup and recovery
Blue Iris backup planning should separate small critical configuration and database information from very large video retention. Version 6 describes a more backup-friendly database structure, but the footage itself can still be many terabytes. The right secondary target depends on which evidence must survive recorder loss and how quickly it needs to be restored.
Quick answer
Back up what would be painful or impossible to recreate
Settings, license details, important database information and selected incident clips are usually more urgent than blindly copying every routine recording. Define the recovery objective before buying secondary storage.

Buying decision
Choose DAS or NAS from the failure you want to survive
A DAS can provide simple local capacity, while a NAS creates an off-recorder network target. Neither is automatically a backup unless the copy is independent and its retention/deletion policy is deliberate.

Blue Iris Backup Storage Planner
Use measured camera bitrate, equipment watts and the retention policy you actually need. The tools use direct unit conversion and planning headroom; they do not invent camera throughput, PoE draw, disk speed or UPS runtime. Verify exact product specifications before purchase.
Compatibility checklist
Four checks before buying surveillance infrastructure
Measure streams instead of guessing
Use actual camera Mbps for storage and network planning. Resolution and codec labels alone do not determine bytes written or link utilization.
Count PoE ports and watts separately
A switch needs enough powered ports and enough total power budget. Night IR, heaters and PTZ movement can change the worst-case load.
Do not convert VA directly into runtime
UPS runtime depends on the exact battery system and connected watts. Use manufacturer runtime data after the protected load is calculated.
Backup must survive a different failure
A second copy is useful when it has an independent retention and recovery path. RAID or another folder on the same recorder is not the same protection goal.
Configuration backup has a different scale from video backup
Recorder settings and important database information are relatively small compared with weeks of multi-camera footage. Protect the small critical state frequently because it is inexpensive to copy and accelerates rebuilds. Decide separately whether the entire recording archive, only alerts or only selected evidence requires a second copy.
Blue Iris 6 changed the database recovery picture
The Version 6 overview describes the database as two files: a smaller file with critical information for backup or rebuild and a much larger, more replaceable file largely containing preview images. That makes it easier to reason about metadata protection, but production procedures should still be verified against the exact installed Blue Iris release before automating backups.
DAS keeps backup close and operationally simple
A USB DAS can hold large local copies without depending on Ethernet or another server. It is convenient for manual exports and scheduled file copies, but it remains physically close to the recorder and can share risks such as theft, fire or a power event. Use it when local recovery speed matters and add another location if the evidence value requires broader protection.
NAS separates the backup target from the recorder
A NAS can live elsewhere on the network, use independent credentials and provide its own storage management. That separation can improve resilience against a recorder hardware failure. It also creates network and authentication dependencies, so the backup window and link speed should be calculated from the amount of data that must move.
Selected evidence deserves a longer retention class
Routine surveillance footage may expire automatically after a defined period, while incident clips can remain valuable for months or years. Move selected evidence into a protected archive with a different deletion policy instead of relying on the normal rolling-recording directory. Label the export with enough context that it remains usable after it leaves the Blue Iris timeline.
A second copy should not share every credential and failure path
If the recorder can silently delete or encrypt the backup target with the same unrestricted credentials, the secondary copy may not protect against software compromise. Use least-privilege access, snapshots or offline/offsite copies where appropriate to the risk. The page does not prescribe one security model because home, business and regulated surveillance systems have different requirements.
Backup bandwidth determines how large a nightly copy can be
A full multi-terabyte mirror every night may be impossible on a gigabit network, while configuration files and event exports are trivial. Estimate the bytes that change during the backup window and compare that with practical network throughput. Incremental or selective copy strategies can protect the important data without moving the complete rolling archive every day.
DAS and NAS capacity need growth reserve too
A backup target that is exactly the same size as today's primary retention set can fall behind after cameras are added or retention increases. Add capacity reserve and monitor free space independently from the recorder. When using a multi-bay enclosure or NAS, plan the supported drive sizes and expansion path before the first disks are purchased.
Recovery time should influence the target choice
A local DAS may restore terabytes faster than a remote network copy, while an off-recorder NAS may survive failures that affect the local chassis. If downtime matters, consider keeping recent critical evidence locally and another copy remotely. Recovery objectives are about how quickly the system and evidence must return, not merely how many backup devices exist.
Verify exported clips outside the recorder
A copy is useful only if it can be opened when the original Blue Iris system is unavailable. Periodically test representative exported files on another machine, verify timestamps and confirm that required codecs or players are available. This catches incomplete copy jobs and format assumptions before an incident forces the first real restore.
Do not confuse RAID inside the backup target with a second backup
A NAS or DAS may use mirrored or parity-protected disks, which can help the target survive some disk failures. The target is still one system. Important footage may justify another independent copy, especially when the recorder and backup target are in the same building or administration domain.
Document the rebuild sequence
Write down where license information, configuration exports, database protection and selected clips are stored. Include credentials, encryption keys and which folders should be restored first. A documented sequence reduces downtime and prevents a rushed recovery from overwriting the only good copy of evidence.
Questions people ask
Blue Iris Backup Storage FAQs
What Blue Iris data should I back up?
Prioritize settings, license information, critical database metadata and evidence that must survive the normal rolling-retention window.
Do I need to back up every recording?
Not necessarily. The answer depends on evidence requirements, storage budget and how much routine footage can be recreated by continued recording.
Is DAS or NAS better for backup?
DAS is simple and fast locally; NAS can create a separate network target. Choose based on failure isolation, capacity, bandwidth and recovery time.
Does RAID count as a Blue Iris backup?
RAID protects against some disk failures inside one storage system. It does not replace an independent copy for other failure types.
How much backup capacity should I buy?
Calculate the data you intend to protect, the number of retained copies and expected growth. Add operating reserve instead of filling the target exactly.
Can I back up Blue Iris over 1GbE?
Yes. The practical question is whether the amount of data fits the available backup window. Large copies may benefit from faster Ethernet.
Should important clips be exported separately?
Yes when they need a retention policy different from routine footage. Keep context and verify the exported files outside Blue Iris.
Can the backup NAS be in the same room?
It can, but that leaves some shared physical risks. Offsite or separate-location protection may be appropriate for high-value evidence.
How often should I test restoration?
Test often enough to detect broken jobs, bad credentials or unreadable exports before an incident. The interval depends on how critical the recorder is.
Why does the catalogue include diskless NAS and DAS hardware?
It keeps enclosure/appliance cost separate from drive choice and avoids silently assuming which disks a marketplace bundle contains.
