When I run the df -h command while SSH'd into my SUSE Linux box I get the following output:
/dev/sdt1, with a capacity of 512G, is mounted on /usr/sap
However, if I cd to usr/sap/<HANA server ID>/HDB00/backup and run du -h --max-depth=1 | sort -hr I get:
Which indicates I have 2.0 TB of data at this location. How can /usr/sap have a capacity of 512G while usr/sap/<HANA server ID>/HDB00/backup is storing 2.0 TB of data? Note that /dev/md125 from the first screenshot has a capacity of 2.0 TB and is completely filled, so I suspect that it is somehow involved here.

I suspect that your /dev/md125 is mounted either at usr/sap/<HANA server ID>/HDB00/backup or somewhere within that folder. If you would like to find out for sure you can run
findmnt /dev/md125
Under TARGET you will likely see a directory withing the usr/sap/<HANA server ID>/HDB00/backup folder.
Otherwise it's also possible that the md device is mounted elsewhere and there is a symlink to it withing the backup directory but this seems unlikely to me because du is set to not dereference symlinks by default. To confirm you could run du -P which will not follow any symlinks (but again this should be the default behavior on most systems)
