TI 2019 -- Reserved copy incrementals are very large
Backup = Daily
Options = Full followed by 5 incrementals, followed by another set, retain 3 sets, make reserved copy, validation on.
Backup is from SSD to SSD, both internal. So it's *very fast. :) Reserved goes to a USB 3.0 gen1 drive.
Two questions:
1. The daily incrementals are, as expected, rather small in size. But the Reserved copies are all as big as the first full backup. Why is that? It could be very space intensive. No, it *will* be very space intensive. :)
2. A complement as much as a question ... As noted, the SSD to SSD backup is blazingly fast, even including validation. But ... the Reserved Copy seems to finish (on a Full backup going to an external USB gen1 device!) at the same time as the SSD to SSD backup. How is this even possible?
