Hi Ron,

df on the new backup machine is now reporting:
[...]/backupsvg-backupslv 1922726712 1825057796 4 100% /mnt/s7backups
total != used+available because some blocks are reserved for use by
administrators (the root user) by the filesystem.
If it's an ext2/3/4 filesystem then you can adjust the number of reserved
blocks with the "tune2fs -m" option. The default is 5% of the filesystem.
Reducing the number of reserved blocks, makes more blocks available for
use by all users.
The number of reserved blocks is:
* Old system: 1894289664 - 1874215424 - 20074240 = 0
* New system: 1922726712 - 1825057796 - 4 = 97668912, or 5% of total
It seems that someone reduced the number of reserved blocks on your old
system to zero.
It's an extremely bad idea in my view to run an ext4 filesystem over 80%
full, as it results in increasing fragmentation over time and there is no
defragmentation tool available.
Cheers, Chris.
