Look at your IOWait. Either you are out of memory or likely your disks are dying.
-
@scottalanmiller what should i do ??
-
@nagendra increasing memory to 32 Gig will slove the issue ??

No, looks like you have enough. But you have an IOWait issue. So you need to figure out why. What is causing your disks to freak out?

Figure out what is using your disks. Your system is spending most of its time dealing with storage issues.

@scottalanmiller i found that there was some hourly backup was running .. it that causing the issue...

That could easily do it, especially if it is not able to complete within the hour window and has overlapping backup jobs.
-
@scottalanmiller correct i stopped the backup process and changed it to daily 2200 HRS backup.. uff thanks scott...

Did that fix the IOWait issue? sar should show it going down in a few minutes.
-
@scottalanmiller
yes
-
Awesome, that was easier than I was guessing that it was going to be.
-
thanks @scottalanmiller
-
Glad that we were able to track that down easily

And how much is being backed up? Might be too much.
-

That's not very much. That should take no time at all. Any idea why it is so slow?
-
@nagendra Okay but what backup are you using? 2 GB per hour is not that bad what we might need to know is the underlying storage and hardware.

And what tool are you using for the backups? Veeam Endpoint? R&R?
