Cloud Backup for Wedding Footage: Backblaze vs Tresorit vs a 4-Bay NAS

A drive failure after a wedding is not a technical problem. It is a professional catastrophe with no remediation. The backup strategy you build before the season starts is the one that either saves you or doesn't.

Most backup conversations among filmmakers start with "what's the cheapest cloud storage?" That's the wrong question. The right question is: if your primary drive dies tonight, how many hours until you have a full working copy, and what does that recovery actually cost in time and money?

For wedding footage specifically, the stakes are higher than almost any other genre. You cannot re-shoot a baraat. You cannot get the bride back into the mandap to re-do the pheras. The footage from a single wedding day, typically 800 GB to 2.2 TB from a two-camera FX3/A7S III setup shooting in S-Log3/S-Gamut3.Cine at 4K 60p, represents something that cannot be recreated at any price.

So here's how a working backup architecture actually looks, and where three common solutions (Backblaze B2, Tresorit, and a local NAS) each sit in it.

The 3-2-1 Rule, Applied to Real Wedding Volumes

Three copies. Two different media types. One offsite. You've heard this. What most people skip is the math that tells you whether your current setup actually satisfies it on wedding volumes.

A 90-minute ceremony shot on two FX3 bodies, both recording internally in XAVC-I 4:2:2 at 600 Mbps, produces roughly 1.1 TB per camera body. Add a wide GoPro locked to the mandap, a stabilizer cam for the baraat, and a wireless lav recorder, and you're looking at 2.4 TB for one day. A four-event package (haldi, sangeet, ceremony, reception) hits 7–9 TB before you've touched the edit.

At those volumes:

• Your "copy 1" is the on-location transfer to two portable SSDs (Samsung T7 or similar) done in the parking lot before you leave the venue.
• Your "copy 2" is an ingested copy on a desktop machine or workstation NAS, where you'll actually edit.
• Your "copy 3" is the offsite cloud backup, which is what Backblaze B2 or Tresorit covers.

The portable SSD copies should happen at the venue, before you drive. Power loss, a car accident, theft from a hotel room, these are not paranoid scenarios. They happen. Get two copies on two drives before you leave the building.

Backblaze B2: The Right Tool for Large Raw Archives

Backblaze B2 charges approximately $0.006 per GB per month for storage, with download costs around $0.01 per GB (and free egress to Cloudflare-partnered services if you route through their CDN). For 8 TB of wedding season footage held for six months, you're looking at roughly $288 in storage alone. Not nothing, but not ruinous for a working professional.

The practical upload path for most solo operators is rclone, a command-line tool that syncs local folders to B2 buckets with multi-threaded transfers. On a 200 Mbps upload connection, 2 TB uploads in about 22 hours. Not fast, but it runs overnight without supervision. The command looks like this:

rclone sync /Volumes/WeddingDrive/2026-10-Sharma-Wedding backblaze:my-wedding-bucket/2026-10-Sharma-Wedding --transfers 8 --checkers 16 --progress

The --transfers 8 flag runs eight parallel uploads, which saturates most home connections. Adjust down if you're sharing bandwidth.

Where B2 fits: raw footage archives, completed project folders, finished deliverable renders. It is a cold-to-warm archive, not a live collaboration tool. You are not meant to mount it as a drive and edit from it. Think of it as your offsite hard drive that happens to be immune to your house burning down.

What B2 does not do: versioning is basic by default (you enable it per-bucket), there is no client-side zero-knowledge encryption unless you add it yourself (Cryptomator is a common pairing), and the interface for non-technical clients or second shooters is not intuitive. If you need to hand a 400 GB folder to a second shooter in Chennai for a remote color pass, B2 is awkward for that workflow.

Tresorit: When Confidentiality Matters

Tresorit is end-to-end encrypted cloud storage with a browser and desktop client that non-technical people can actually use. The encryption is zero-knowledge: even Tresorit's servers cannot read your files. For wedding footage, this matters when you're handing pre-edited footage to families or sharing raw files with associate editors.

Pricing is meaningfully higher than B2. The Business Solo plan (as of 2026) runs around €24/month for 2.5 TB. You hit a ceiling fast on wedding volumes, and paying for additional storage puts you in a different cost bracket than rclone-to-B2.

Where Tresorit fits: client delivery folders, contracts, model release forms, anything with faces and legal sensitivity. Share a Tresorit folder with the bride's family for their sneak peeks, and you've handled both the delivery channel and the privacy question in one step. The upload speeds are slower than a raw rclone job because of the encryption overhead, but for 50–80 GB delivery packages it's manageable.

What Tresorit does not replace: a bulk archive for your 8 TB raw season. The cost-per-TB is too high, and the upload client is not optimised for multi-hundred-gigabyte bulk transfers the way rclone against B2 is. Use it selectively, not as your primary backup tier.

A 4-Bay NAS: The Foundation Everything Else Rests On

A Synology DS923+ with four 8 TB IronWolf drives in RAID 5 gives you 24 TB usable, one drive's worth of redundancy, and a price point around ₹90,000–1,05,000 all-in depending on current drive prices. It is not cheap at entry. It is very cheap per TB over three to five years of use, and it is the only solution that gives you gigabit LAN transfer speeds when you actually need to pull footage at 3 AM before an early morning shoot.

The workflow on a NAS-centred setup:

1. Ingest from portable SSDs to NAS over LAN (typically 100–110 MB/s on gigabit; 2 TB in about 5.5 hours).
2. Edit directly from NAS shares mounted on your workstation. XAVC-I at 600 Mbps is roughly 75 MB/s, comfortably under gigabit.
3. Run Hyper Backup on the Synology to push a compressed, deduplicated backup to Backblaze B2 overnight.
4. Keep the original portable SSDs in a separate physical location (a studio drawer, not the same bag as the laptop) until the project is delivered and archived.

RAID is not a backup. RAID protects against a single drive hardware failure. It does not protect against a ransomware infection that encrypts every file on your array, a power surge that takes out multiple drives simultaneously, or theft of the entire unit. That is why step 3 above is mandatory, not optional.

Synology's Hyper Backup to B2 is one of the cleaner integrations available. It supports incremental backups (only changed files after the first full upload), encryption before upload (your key, not theirs), and restoration both at file level and full-volume level. Setting it up takes about 45 minutes and then it runs quietly in the background every night.

The On-Location Triage Protocol

The gap where most footage loss happens is not a drive failure six months later. It's the 48 hours immediately after the shoot, when cards are half-copied, drives are not labelled, and the team is exhausted. A protocol that runs without thinking is the one that actually gets followed.

Before leaving any venue:

• Cards ingested to SSD 1 (primary): confirmed by file count and total size matching the card's used space.
• Folder duplicated to SSD 2 (mirror): not copied and assumed; verified by running a quick checksum comparison or at minimum confirming folder size is identical.
• Cards not formatted until SSD 2 is confirmed. Not after dinner. Not in the morning. Before the cards go back in the bag.

For checksum verification on macOS, shasum -a 256 on a representative sample of large files (the biggest .MTS or .MP4 from each card) takes under a minute and catches silent write errors that a simple file copy will not.

Some teams use Hedge (macOS) or ShotPut Pro for on-set ingest with built-in verification. Both are industry-standard tools for exactly this problem, and both generate ingest reports you can keep with the project file. At ₹12,000–16,000 for a license, they pay for themselves the first time they catch a corrupt ingest before you've formatted the card.

What a Real Season Archive Costs

For a 20-wedding season producing roughly 160 TB of raw footage before archiving (some gets culled, delivered projects get compressed renders stored separately), a rough annual cost breakdown looks like this:

• Backblaze B2 for 80 TB (assuming 50% culled/compressed for long-term archive): ~$2,880/year in storage. Add some egress for occasional pulls: budget $3,200.
• Synology NAS expansion drives (adding capacity as the array fills): one 8 TB IronWolf every 18 months at roughly ₹16,000 each.
• Portable SSDs for field duplication: two per season, retired after two years. Samsung T7 2 TB at roughly ₹9,000 each.

Per wedding, that archive infrastructure works out to roughly ₹1,000–1,800 per event. For a package priced at ₹80,000 and up, that is not a margin problem. It is a cost of doing the job correctly.

The Recovery Test You Keep Forgetting to Run

A backup you have never restored from is a backup you do not actually have. At least once per quarter, pick a random 50 GB folder from your B2 archive, pull it down over rclone, and verify the checksums match the originals you still have locally. This takes about two hours of download time and 15 minutes of attention. It confirms that the upload completed correctly, that your encryption key is still accessible, and that your rclone configuration still points at the right bucket.

Do the same with your NAS: restore a test folder from Hyper Backup to a different directory and confirm the files open correctly. Synology's restore interface is straightforward, but running through it under calm conditions means you know what to do if you ever have to run through it under pressure.

The photographers and cinematographers who lose footage are almost never the ones who had no backup system. They're the ones whose backup system had never been tested and turned out to have a configuration error that silently failed for six months. Test it. Put a reminder in your calendar now.

For more on the full kit ecosystem that supports a two-person wedding team in the field, the FX3 vs FX6 breakdown for two-person teams covers how camera choice interacts with your ingest workflow, and the Resolve vs Premiere speed comparison on M2 Pro covers how your NAS storage speed affects the edit timeline directly. Both are worth reading alongside this before you commit to hardware purchases for a new season.
