I know its probably not your fault, but this is a sysadmin best practice (though, if you read /r/sysadmin, you'll see they regularly don't do this either). Backups are useless unless you regularly validate them. Backups can break in many different ways, and you don't want to find out that they broke when you truly need them. This obviously increases cost/time for using a service/solution, but its good to do to hope it does work when you need it.
- brewdad 5y agoThe whole value proposition of Backblaze and similar services is that I don't have to have sysadmin levels of knowledge. It just works. If I wanted to deal with regular validation of backups and similar sysadmin tasks, I'd just run the whole thing myself.
- 1123581321 5y agoIt takes like an hour a year to request a USB stick from Backblaze, browse through it and return it. Validating backups on top of rolling your own would take a lot more time (i.e. the value proposition is more complex.) There’s really no “it just works” in backups of data you care about unless you have people you can delegate the restore testing to.
- bradknowles 5y agoHow do you know for sure that the stick they send you is a valid restore snapshot? Do you have a program you wrote to go verify the contents of each and every file on the stick and compare that to what is currently on your system? It seems to me that the backup validation process also has to be provided by the vendor that created the backup software itself. Only they know their file formats. Only they know how to properly compare file A and file B to see if they are correct and accurate.
