Azeem:

0516 is known to be a stable version. Now you mention that the post firmware updates has caused your backups to degrade/slow down.
Could you kindly tell us as to what is the backup software you are using. Next, if possible run L&TT and perform the drive assessment test and do let us know if the test indicated any warnings/errors.

* Also, are the backups timing out, i.e., failing?


Thanks
