Frankly, expecting a UPS to carry for 2 hours is an unreal expectation.
I did have one that could do that at one time, an old 200+ pound NCR
branded thing I had installed a quartet of 14AH wet L-A batteries in,
making arrangements to handle the overflow tubes by directing then into a
pint jar half full of soda. It worked well but floated the wet batteries at
too high a voltage and ran them dry at 6 month intervals, so that was about
$120 2x a year to keep it running, even after I found the float setting and
turned it down 2 volts to 52 volts. So for several years and quite a few
battery packs, I have used a pair of 1500wa rated UPS's that I can get
batteries for at a lot less at 2 to 3 year intervals. With the load here,
I have about 5 minutes to do a graceful shutdown else it drops the line in
less than 10. The modern ext3 file system tolerates that well and I have
not had to fsck a drive at other than the scheduled intervals in many years
now unless the drive itself was on its way out.
If you want a 2 hour holdup time, be aware that it tends to cost real money
both at purchase time and at maintenance time. It is not going to be $350
in pocket change, but more likely in the 10 grand range for commercial rack
