Whatโs the current cost of data backups these days? Iโm guessing itโs less than $600,000, even for an entire cityโs worth of data. https://t.co/1d5BuLwjfm

I can answer this!
But first, most places are terrible at backups, and itโs (usually) not the fault of IT. Itโs often lack of budget โ leadership does not prioritize backup as it looks expensive on paper and isnโt needed often. But when it is needed, damn you really need it.
So letโs look at a small city like Riviera Beach. Itโs got about 35,000 residents and probably around 350 city employees (full and part-time). Thatโs at least 400 workstations to back up. The workstations, though, arenโt that important comparatively. Still, weโll include them.
Itโs hard to know the exact IT infrastructure of a town โ it varies too much. But we can make some guesses and generalizations. A small town will be keeping long-term records (usually in PDF or TIFF format), do GIS, HR, etc., and all the ancillary data to support that. Say itโs 50,000GB, total, just for the server systems. Thatโs 50 terabytes of data that would be vital to city. Again, thatโs just a guess, but I bet I am not too far off (been working in IT a long time).
If their IT department is competent enough, they can build a 100TB NAS dedicated to backup for about $7,000. Use something like Veeam Backup and Replication to back up the vital server systems โ that should enough to keep about 180 days worth of backups. Veeam would add about $10,000 in licensing to that cost.
Thereโs $17,000.
For long-term backups (usual dance of monthly/yearly/every seven years), you would need to go offsite, of course. Backblaze B2 storage is a good choice for this. A year of this for 50TB of data plus monthly increases would be about $3,050 a year.
The 400-ish workstations are a harder task, but also far less important. I wouldnโt consider backing up the entire workstation โ too expensive what you get. Iโd set a policy of only backing up user profiles, and only certain folders at that. Thatโd be about 10TB of user data also on our NAS, which should fit fine with de-dupe and compression. First, Iโd put it on that aforementioned backup NAS and then Iโd move it also into B2 storage, with a 180 day-retention period.
Thatโs another $640 a year.
So, letโs look at our backup costs:
Server/infra backup: $17,000.
Offsite long-term: $3,050
Workstation backup: $640
Labor/setup (est): $40,000 (assuming two employees take two months to set up all this and cost is $100 per hour. This is probably an overestimate because I could set this all up by myself in about two weeks)
Cost of decent backup, including labor: $60,690
Cost of paying hackers: $600,000
Savings from good backup: $539,310
As I noted, there a lot of assumptions and unknowns here. I can guarantee, though, that my costs and estimates arenโt that far off.
