Notice that the first full is 78GB, but the incr is 276GB. I would guess you added shares, directories or changed excludes after the full, but before the incremental. Or a large amount of data was added between these two backups. > 3 incr 3 900.7 530.7 41.1% 964.7 469.5 51.3% > 4 incr 3 113.5 2.7 97.6% 218.0 30.8 85.9% > 5 incr 3 73.4 6.1 91.7% 194.8 32.2 83.5% > 6 incr 3 304.3 172.2 43.4% 1735.9 944.0 45.6% > 7 incr 3 275955.3 165019.1 40.2% 1337.0 658.0 > 50.8% > 8 incr 3 520.4 249.4 52.1% 672.7 282.5 58.0% > 9 incr 3 502.9 243.5 51.6% 587.6 264.1 55.1% > 10 incr 3 116.8 3.7 96.8% 201.5 24.3 88.0% > 11 incr 3 14.0 3.0 78.7% 244.3 32.8 86.6% > 12 incr 3 127.1 5.3 95.9% 82.2 22.3 72.8% > 13 incr 3 276989.9 165643.4 40.2% 329.3 40.7 > 87.7% > 14 incr 3 275957.9 165146.0 40.2% 1503.5 615.1 > 59.1% > > My question is, why did backups 13 and 14 backup all that data?

Since the full (#0) has a much smaller set of files, those level 1 incrementals are backing up a lot of data, and a lot more than the original full. Bottom line: you need to do a full backup. It's going to take a while (but no longer than the incrementals). After that, the future fulls and incrementals will be a lot faster. Doing a full backup is good practice if you make a significant configuration change that significantly changes what is being backed up, or add a large amount of data.
