Cost Estimation Calculator
Since, the price is in GB, each month, it a bit hard to understand the advantage. Let’s take “big WordPress customer” and do an estimative calculation. Assume a database big enough to have a 1GB archive file PLUS 100 GB of files under the hood, inside WordPress. Hourly DB backups and daily full backup is an extreme approach, but let’s crunch the numbers. Database: 1GB X 24 hours X 31 days = 744 GB/month. Files: 100GB X 31 days = 3100 GB/month. Both would be 3844 GB/month. Total Estimated Cost: €325.98 per 1 month for Cloud Files space.
Now, let’s consider, that we don’t need ALL the existing backups, just the last 7 from each (database and files). This means we need to delete existing archive files when we have old unwanted ones. Database: keep only last seven backups for each last 7 days (not the last 7 from last day), and delete the rest. Crunching the numbers for database: 744 GB/month – last 7GB = 737 GB/month. Same logic for files: 3100 GB/month – 700 GB = 2400 GB/month. Both would be 3137 GB/month. Total Estimated Cost: €266.02 per 1 month for Cloud Files space.
Now, let’s consider, that somebody will crash the hosting server and erase everything, weekly. Then, you need to restore everything, weekly. If this happens to you, then consider switching immediately to owl power, as this is a borderline crazy scenario! Restoring would mean to download 5 times in a month a single database archive and a single file archive; always the last one, right before the server crash. Crunching the numbers for database: 1GB X 5 times = 5 GB/month PLUS for the files: 100 GB X 5 times = 500 GB/month would add up to a 505 GB extra Download cost. Your previous bill will jump from previous amounts to a whopping €51.36 just for Cloud Files restore, as extra Cost.
Total Cost for 1 Month is €317.38, at the end of this scenario. Kinda costly, right?
