Short answer: the best way to store video footage long term is three copies on two kinds of media with one off-site, the 3-2-1 rule, because every single medium fails in a different way. Hard drives die mechanically after three to five years on a shelf, SSDs lose data unpowered within a year or two, NAS arrays protect against one disk failing but not against fire, theft or a wrong delete, and cloud archives cost more per TB per year than any drive. Combine them and nothing fails at the same time.
What fails first, and how?
Portable HDDs fail mechanically. Bearings, heads and the spindle motor degrade whether or not the drive is used, and a drive that has sat unpowered for four years may not spin up. HDDs also suffer bit rot: individual sectors go bad silently.
External SSDs are fast and shock-proof but store data as charge in cells that leaks over time. The industry design standard for consumer SSDs is one year of data retention unpowered at about 30 °C; in practice it is often longer, but no manufacturer promises it. An SSD is a working drive, not an archive.
A NAS with RAID survives one or two disks failing. It does not survive the power supply failing and taking the array with it, a controller fault, ransomware on the office network, a flood, or an editor deleting the wrong folder, because RAID copies the delete too. RAID is redundancy, not backup.
LTO tape is the archival medium of broadcasters: 30-year rated shelf life, 18 TB per LTO-9 cartridge. The drive costs several lakh and a small studio rarely has the volume to justify it.
Cloud archives do not fail physically, because the provider keeps multiple copies and replaces hardware silently. They fail when the account lapses or a retrieval fee makes you hesitate to pull a project back.
What does each option cost per TB per year?
| Option | Purchase cost | Cost per TB per year, single copy | Useful life | Watch out for |
|---|---|---|---|---|
| Portable HDD, 5 TB | ~₹10,000 | ~₹400–500 | 3–5 years on a shelf | Bit rot; must be spun up and checked yearly |
| External SSD, 2 TB | ~₹15,000 | ~₹1,500 | 5 years powered; ~1 year unpowered | Not an archive medium |
| 4-bay NAS with 4 × 8 TB disks | ~₹1,00,000–1,40,000 for ~24 TB usable | ~₹1,000 plus ₹3,000–5,000 a year in power | 5 years, then disks age out | RAID is not a backup; someone must maintain it |
| LTO-9 tape | Drive ₹3–5 lakh; cartridge ~₹8,000–10,000 per 18 TB | ~₹500 for media, plus the drive amortised | 30 years | Only sensible above ~100 TB |
| Big-cloud cold object tier | None | ~₹1,200–4,800 at list | Indefinite | Retrieval and egress fees of several thousand rupees per TB restored |
| Driveless archive tier | None | ₹7,188 (₹599 per TB per month) | Indefinite | Three copies kept; still opens in Finder; GST extra |
A shelf of HDDs is the cheapest medium by a wide margin, even after buying two of everything. The cloud’s price buys what a shelf cannot: off-site from day one, verified continuously, and dependent on nobody remembering to spin the drives in March.
What does 3-2-1 look like for a video library?
Three copies of every finished project. Two different media, so a fault that kills one kind does not kill both. One copy somewhere else, so a fire, a theft or a flood in the office does not take everything.
For a solo creator: the working copy on an external SSD or a streaming cloud drive, a second copy on a 5 TB HDD in a cupboard at a family member’s house, and the third in a cloud archive. For a studio: the working library on a NAS or a cloud drive with a studio cache, a cloud archive for delivered projects, and a set of HDDs rotated off-site each quarter. How much storage a wedding videographer needs works through how many terabytes a season produces, which decides how many of each you need.
How do you keep a shelf drive alive?
Label it with the contents and the date. Once a year, plug it in, let it mount, open a few files from different folders and let them play. Better, keep a checksum file alongside the footage and verify it; a mismatch is bit rot, and the fix is to re-copy that file from another copy while you still have one. Retire the drive at five years and copy its contents to a new one.
What should go to archive, and when?
Not everything. Keep every original camera file for delivered projects, the final master, the project file and the graphics. Delete render cache, previews, proxies and draft exports; they are regenerated from the originals if the project returns. How to organise a video footage library sets out a folder structure where a project folder is archive-ready the day it is delivered. Move projects to archive within a month of sign-off and agree a retention period with each client.
Where Driveless fits
Driveless is a streaming cloud drive for Mac, launching in India in January 2027. Delivered projects stay in the same library as active ones, browsable in Finder at 0 KB on the Mac, and the Studio plan’s archive tier is ₹599 per TB per month for footage you must keep but rarely touch, with three copies kept, versions, a 30-day trash and daily snapshots. The waitlist is open; every plan is on the pricing page.
Frequently asked questions
What is the best way to store video footage long term?
Three copies on two kinds of media with one off-site. For most Indian creators and studios that is one working copy on a drive or NAS, one copy in a cloud archive, and one cold drive on a shelf that is checked once a year. No single medium is safe on its own for more than a few years.
How long does a hard drive keep data on a shelf?
A portable HDD stored unpowered in a dry cupboard is reasonably reliable for three to five years, with failure rates rising after that. A consumer SSD is designed to retain data unpowered for about a year at room temperature and should not be used as a shelf archive. LTO tape is rated for 30 years.
What does cloud archive storage cost per TB in India?
Big-cloud cold tiers list at roughly ₹100 to ₹400 per TB per month before retrieval and egress fees, which can add several thousand rupees per TB restored. Driveless’s archive tier is ₹599 per TB per month with three copies kept, and the archived file still opens in Finder like any other.
