Use the force, change to a better FS: XFS (w/ the inode64 switch on)
eg: laptop 500GB HD filled @ 80% with many small pictures and dev files,
df -i returns:
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda2 388630464 1265847 387364617 1% /
XFS is also capable to raise the inodes quantity in one command
while the partition's mounted.

Best way to know: test it…

google 'inode' to know exactly what it is.

This is entirely YOUR fault, 'cos before establishing a backup system,
an admin has to analyze what the data is made of, with the aim of what
he's gonna do with it. Counting the number of files and their size to
process is backup's 1.0.1, while checking if you have enough room &
inodes on the backup device is 1.0.2.
Not to mention that some self-researches & readings can help.
