Time Machine slow after 6.5.2 update

I disabled the Antivirus service on the Readynas, and that had not decernable effect.  Is there a way to see what is being backed up or a way to watch the log in real time.  I can see when the backup grinds to a halt and the extimate times changes from 1 to 2 to 3 hours and then eventuall an MB or two complete and the estimate dropes back down.  This is truely odd. 

Currently the services that are running are SMB, AFP, ReadyDLNA, Rsync, HTTP, HTTPS.   Keeping in mind my current uses for the NAS:

1. I am running mac software like itunes (Library is on a share) and MS Office for Mac (file storage on NAS)
2. Using Parallels Virtual Machine to run Windows 10 and office 2016, storing files on the NAS
3. Attaching a USB3 portable hard drive to back up the NAS files.
4. I have tried connectign to the NAS remotely using ReadNas Remote, but not had much luck with it due to firewalls at clients.  So this not a need.

I think I turned on Rsync when I got the NAS to transfer the files from the old NAS to this one, can I turn that off now?

You can.  Some people use rsync for USB backup, so check the backup job for that first.

StephenB,

I am using the back up jobs created on the NAS, triggered with the front button after connecting the drive.  I do not see inthe settings and mention of what protocol the back job uses.

So do the slow downs for TM backups coincide with writes to the NAS from other applications?

You'd likely remember if you'd set up the USB backup job to use rsync.

To see the method, select the backup job, then click the settings wheel.  Look at the Source and Destination, and you should see the method in the "name" field.  If you don't see "remote:Rsync Server" on of those pages then you aren't using rsync.

For instance: 

StephenB:

Based on the picture, then I would say the backups are not using that protocol.  But I cannot be sure which of the others it is using:

If both the source and destination are local, the system is using linux copy [cp] commands.

You could have treated the install share as remote (using 127.0.0.1 as the remote IP address), and then chosen rsync as the protocol.  There are some advantages to that (but it is off-topic).  The main thing is that you aren't using rsync, so you can disable it if you like.

I have not turned of the Rsync protocol yet, as I was in the middle of timing a back up.  It seems things are worse now than when I last wrote.  I manually launched backup, all the network and machines are the same.  The only difference is that I did not run a virtual machine inbetween the previous and this back up, I did not connect to the shares at all.  I rebooted the iMac and launched the back up.   2.67GB  and it took 7:47 minutes!

This is a bit geeky, but here is a table of times that I managed to catch.  The final entry was within minutes of it ocurring.  

I am warming up a MacBook Pro laptop that i will conenct to the network the same way and will try a TM backup for it as well and see if there is any major differences.   

Ok, A test with a second computer was better, but still not the norm.  The was using a MacBook Pro that is 4 years older (slower processor) connected by Ethernet cable to the same switch/router/NAS that the iMac is connected to.  No other programs running. No other machined connected to the Shares on the NAS.  The backup was 2.07 GB and took 2 Hours and 28 mintues plus an additional 1hr and 16 min for a verification step.

In my mind, this shows it is not a device (iMac or MacBook) problem, but I think related to the NAS update that noted at the start of this thread.

Here is the table from the Backbook:  

Good day,

Based on the description of the issue that you have provided, I may need to check this with others who can probably assist you and get back to you as soon as possible.

May I also ask if the NAS overall is showing any type of slow response other than the Time Machine back-up.

Thanks for your cooperation!

I copied (drag and drop) a 4.01 GB Aperture Library from my iMac to a share on the drive (AFP). Mac OS esitmated that it would take 4 mintes just after starting. Its progress seemed to fast until about 2GB mark it was 2:minutes and it slowed at that point.  it hit 3GB  at 4:40.   It finished all 4 GB at 5:48. MUCH faster than the documented Timemachine job close to what I expected.

I thought I had this in my original post.  But cannot see it.   My Rig:

I have the WiFi on the iMac turned off for all the testing.  The longest cable run is 20 feet, the rest are 8 or less. All using Cat 6 cable.

FramerV,

Its been awhile since I have see you post, did you check with the other people and did you find any additional information?

As an update to my situation, i have updated to Sierra and that made no change.  Today I updated Sierra to 10.12.2 and tried initiatign a time machine back up and after 2 hours it is still preparing the backup.
