I'm a database guy. I don't deal with infrastructure/ sysadmin stuff (although obviously it ties in together a lot).
If I'm backing up say SQL Server to enable a certain amount of recoveries -- say every day for 14 days, and once a month for 12 months .... X amount of backups.
And there are server level backups ... I don't know what those are ... similar idea though, there are daily, weekly, monthly recovery points .. Y amount of backups.
If my backup storage takes my database(s) total size --- say 500 GB .... and ends up taking that to 1500 GB... 3x size.
And the infrastructure backup model takes the total server size and takes that x3 size (I'm actually not certain and haven't exactly looked into this --- yes accidental DBA indeed).
Then presumably our full backup plan is X * Y right? 9x?
Is this a dumb way to do backups?
