Safest Way to Store 40TB of CCTV Footage

Post by Rippermaster »

I'm Looking to store 60 days of footage of 14 cameras at 720p a calculator estimated that to be around 36tb of footage aside from the immense cost I'm also looking to have it in RAID just in case one drive fails what is the safest way to go about this? what raid settings should i use also open to any other suggestions for storing this amount of footage on a network without having a proper server

all sequential stuff..so any system with 6 or more spinning disks should have no problem

so a system with 6*8TB disks in RAID5 should be able to hold 40TB (actually 90% of that due to losses and calculation differences) so you could bump it up to 10TB disks or get a NAS with even more bays

So what is your budget?

main nas to store it. then have a 2nd for backup. then a 3rd for offsite. this is called the 3-2-1 backup strategy. in terms of backup, this is one of the best.

or if you want to save cost, then main nas + backup offsite. downside is, there is no quick backup option, since you only rely on a offsite backup.

or main nas + backup onsite (with risk that if there is physical theft, then your backup might get compromised)


or if you are being really cheap, then just a main nas only. just keep in mind that raid is not a backup... so if anything happens (it's not if, it's when. usually when hdds die, or raid rebuild issue, or malware issue, or some other reason requiring a reinitialization), chances are you could lose your data stored.

while at it, maybe your backups can be encrypted, like client side encryption? especially for offsite backup, because usually you have less control for offsite (especially if it's a cloud service), then encrypting that backup protects your data from being accessed without the necessary credentials to decrypt the backup :)

Using what video codec? And what bitrate?
Possibly h.264, in which case if you use h.265 or even a proprietary h.265+ you will reduce the storage requirement by a factor of several, with the same video quality.
Also - for CCTV footage, you're not shooting a movie, so having the FPS at 15fps or so allows either better quality for the same bitrate, or a lower bitrate for the same quality than if you max out the FPS.

It's purely the bitrate that determines the storage consumption, so you can tune it for whatever your primary aims are.
TS-431+ for storage and media and a bunch of IP cams under Surveillance Station. TVS-473 as files backup and QVR Pro.
