Use a tiered plan: keep your working library on primary storage, make a separate local backup, and keep another copy off-site. Before buying anything, measure the library, estimate how much it will grow, and decide how long you need to retain older or deleted files. That makes it easier to choose storage you can actually back up and restore.
Build a backup plan around the library you have
A practical starting point is the 3-2-1 approach: keep three copies of important data, use two types of storage, and keep one copy off-site. Backblaze illustrates this with a computer, an external drive and an online backup in its 3-2-1 backup guidance. Treat the numbers as a planning principle, not a requirement to buy a particular device or service.
Start by measuring the current library, then estimate new footage over the period you want a storage device or plan to serve. Decide whether your backup must preserve older versions and files you delete from the working library. Size each copy separately: the off-site plan may use a different storage model from the local copy, and retained versions can require more space than the current library alone.
- Record the library’s current size and where it lives.
- Estimate future additions over your planning period.
- Choose whether older versions and deleted files need to remain recoverable, and for how long.
- Check usable capacity, filesystem and operating-system support, and how the backup software handles updates and retention.
There is no evidence-based universal drive size or headroom percentage for every video library. Also, do not count on compression to solve a capacity problem: already-compressed video may have little room for lossless reduction, while lossy transcoding changes the footage. No dependable video-specific compression ratio is established here.

Choose a local backup that fits your setup
External hard drive
An external hard drive is a straightforward way to keep a separate local copy. Choose its capacity from your inventory and expected growth, then confirm its connection, filesystem and operating-system compatibility. A drive only protects recent changes if it is connected often enough for the backup job to run; a drive left disconnected for long periods can become stale.
NAS
A NAS can centralize a growing library or make it available to multiple users. Its drive redundancy may help keep the files accessible when a drive fails, but the NAS itself is not an independent backup. Configure another destination, such as an external drive or an off-site service, and verify support for your exact NAS model and backup app.

Make the off-site copy recoverable in practice
Cloud backup and object or archive storage can provide an off-site copy, but they differ in setup, retention and retrieval. AWS describes S3 as usable for backing up individual files, servers or a data center and includes S3 Glacier Deep Archive among backup and recovery options. That guidance does not establish which service is cheapest or best for a particular library; compare the terms that determine whether you can recover your footage when needed.
| Option | Useful for | Check before choosing |
|---|---|---|
| External hard drive | A separate, local copy | Capacity, interface, filesystem and operating-system support, and how often it will be connected |
| NAS | Central storage for a growing library or multiple users | A second backup destination, plus compatibility for the exact model and software |
| Cloud backup | An off-site copy managed through a backup workflow | Source-drive and NAS support, retention and version history, upload and restore duration, and price |
| Object or archive storage | Potentially scalable off-site storage, often paired with backup software | Setup complexity, lifecycle and version rules, retrieval time and charges, and compatible software or NAS integration |
Before settling on a service, check whether it accepts the device or volume you are backing up, whether it preserves versions for long enough, and how long an initial upload and a full restore may take on your connection. Include any retrieval or restore charges in the comparison. A backup that is too slow or costly to recover may not meet your needs.

Check large-file behavior and device compatibility
Backup products handle large files differently, so verify the documentation for your chosen service rather than assuming all cloud storage works alike. Backblaze’s Computer Backup documentation says files larger than 100 MB are divided into 10 MB chunks for transmission. Its example also describes temporary working space related to file size and notes that a temporary data drive can be selected. That can matter when the computer running the backup is low on free space, but it is specific to that product.
Backblaze B2 documents a separate large-file workflow: its “Large Files” documentation says, “Large files can range from 5 MB to 10 TB which is well beyond the 5 GB limit on normal files.” Those limits apply to B2’s large-file process, not to cloud storage generally.

- This USB drive provides plug and play simplicity with the included 18 inch USB 3.0 cable
- The available storage capacity may vary.
Compatibility is equally product-specific. Backblaze says its Computer Backup supports qualifying directly connected external drives, subject to its requirements, but excludes NAS devices and network-mounted drives. Its help documentation says a backed-up external drive must be reconnected at least once every 30 days under the default 30-day version history if its data is to remain available. Backblaze says B2 can be used to back up network drives; this distinction should not be generalized to other providers. See its external-drive requirements and NAS and network-drive guidance.
For Synology owners, Synology’s 2023 backup guide lists external hard drives, cloud and rsync destinations, and includes Backblaze B2 among Cloud Sync services. That is guide- and product-specific: verify the current app and your NAS model before relying on the combination. The guide is available at Synology’s data backup page.

Estimate the real cost in time and recovery
Storage capacity is only one part of the decision. A large first backup may take substantial time to upload, and restoring a full library may take longer than retrieving a few files. Compare ongoing storage expense, upload bandwidth and duration, retention settings, source compatibility, restore speed and retrieval charges. Costs vary by provider, plan and geography, so use the current official pricing and service pages for your location rather than relying on a generic price comparison.
Keep a local copy for practical access to large files, and treat the off-site tier as protection against events that affect the local equipment as well. A sync folder or RAID can improve convenience or availability, but neither by itself guarantees an independent backup: synchronization may also propagate unwanted deletions, and redundant disks in one system do not create a separate off-site copy.
