Redundancy and risk

Redundancy

Two are better than one (at least that’s what a hebrew sage wrote 3,000 years ago) – he goes on to say 3 are even better. Looks like not much has changed in three millenniums. Don’t you copy your data to a second drive? Actually you should follow the 3-2-1 Backup rule: 3 copies, 2 different medium, 1 offsite copy. See? The jewish king was right: 3 copies. Today we talk about single point of failure and built-in redundancy. Limit risk by having a plan B and C. You don’t want to say no to a client, because you go to experience a single point of failure.

On location

The ioSafe rugged portable drive can sit underwater for a few days.Case in point: The hard drives that go on location with me are ioSafe drives. You can drop them from 10 feet, it takes over 5,000 pounds to crush them and they are waterproof – submersible to 30 feet for 3 days. Physically there’s no drive that keeps my data safer in the field (and yes the ioSafe drives I use for my day-to-day backup in the office are fireproof on top of that.) I carry two copies of all data on multiple drives in addition to the copy on my laptop.

When I travel back from location one of those two drives does not travel with me. It either travels on another plane or it get’s FedExed back to the studio. Three copies (laptop and two hard drives), 2 media (SSD and HD) and one in an offsite location). 3-2-1 backup rule – check.

Once the ioSafe drives come back to the office to get copied onto a Synology RAID system, which in itself is redundant. Mine has five 4TB Western Digital Red drives in it, that are set up so that one drive can physically fail and no data gets lost. All I have to do is to slip in another drive and the RAID will rebuild itself.

Tech Tip: Remember to back up

The trick is remembering to back up. All the hardware in the world does you no good if you don’t use it. Better yet, set up a system that automatically backs up your jobs (SPOILER ALERT – I’m gonna look at how automation can help you run a more efficient business over the next few weeks – stay tuned …)

Automate your backups

Every night at 3 am, I have a little elf that wakes up my computer and copies all files from that day onto my RAID.
