Yes, no, and maybe. Unfortunately, you have to try it.
You can calculate the theoretical maximum transfer rate, but you rarely actually get that.
How big are the files, and how long does it take? What are you backing up? What OS?
Often the bottleneck isn't the actual electronic data rates. For instance, when backing up lots of small files, the actual data rate is slow because the OS takes a lot of time handling the file creation or access process. There's a little overhead for each file.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
How much drive space is left on the NAS?
Using FlashAir W-03 SD card in machine. Access through wifi with FlashPAP or Sleep Master utilities.
I wanted to learn Binary so I enrolled in Binary 101. I seemed to have missed the first four courses.

What type of daily backup are you making; full, incremental or a clone update? I find using XXCOPY with the /clone switch to be the fastest method for backups if no compression is needed. Not a bootable copy but great for data.
Starting with Win7, all bootable backup times are much slower than previously, even a daily incremental can amount to several Gigs since the system is quite active when doing very little. It may have something to do with the automatic defrag feature although I have never pinned it down to anything in particular.
I'm using ROBOCOPY to make a copy of all significant places where data are stored.
That's the copy that's slow.
A typical command line is:
ROBOCOPY "%PUBLIC%\Documents\ResMed\ResScan3\Patients\Mongo, Just" "\\%NASNAME%\%MNAME%\%FN%\Mongo, Just" /S /E /R:0 /DCOPY:T /NP /LOG+:%ELOG%
Then, by Wireless N, I update files on a second machine -- it's quick because a date-time stamp is compared; and a copy is done only if a newer file is in the backup on the NAS.
Typical command line: (note the XO switch)
ROBOCOPY "\\%NASNAME%\%MNAME%\%FN%\%XFOLD%" "%PUBLIC%\Documents\ResMed\ResScan3\Patients\%XFOLD%" /S /E /XO /R:0 /DCOPY:T /NP /PURGE /LOG+:%ELOG%
Once a week, I use the Windows backup utility to create a disk image on an exterior drive over USB 3.

Carry on. It looks like your speed issue will rest with whatever speed is being negotiated over the network based on the load imposed.
