FYI: A comparison of Disk vs File backups
Today I got my new external drive for doing some offsite backups. My first backup was for my D: drive which is all data.
I created a File and Folders task to backup everything on the drive except for 5 folders. Here are the timing results from that backup task:
File size: 183,853,704 KB
Backed up: 202.5 GB
Speed: 499.5 Mbps
Time spent: 51 minutes, 2 seconds
Data to recover: 202.5 GB
Validation time: 32 minutes
I then created a Disk level backup for the same data with these results:
File size: 183,865,711 KB
Backed up: 203.4 GB
Speed: 898.4 Mbps
Time spent:29 minutes, 7 seconds
Data to recover: 202.5 GB
Validation time: 26 minutes
In both cases, the system was nearly idle.
I find this difference significant.
