Latest update causes backup to run really slow

Thread needs solution

Hi,

Running windows 10 pro on my dell 7746 laptop with a samsumg SSD 840 512 gig with 24 gig memory. The drive is less then 1/2 full.

When I did a full backup before the update it would take less than a hour from start to finish. I did a full backup yesterday and it took like 3 hours to finish. Before I do a backup I always clean the temp files and all the stuff that I do not need to backup.

Any help on this,

Thanks

Jack, which particular update are you referring to for this problem?  Is this a Windows Update or is it an Acronis Update?

What type of full backup are you performing here?  Is this 'Entire PC', or Disks & Partitions, or Files & Folders?  Does this include Incremental or Differential backups inbetween doing Full backups?

What are the sizes of the backup files created before and after the 'update' you are referring to?

 

And where is the backup being written to?  USB, NAS, etc.  How much space on that drive...

Was the new backup the same size as previous backups or considerably larger (referencing a sector by sector backup instead of a regular backup of only the used data).

Did you restart your laptop after the update?  You should so that certain changes made to the installation will take full effect.

Hi Steve,

I updated Acronis to v 8041 and backup with disks and partitions with Differentials inbetween.

Both of my backups were full backups I alway do a full backup with a new build.

Jack, thanks for the further information, the file sizes look very similar so don't see a problem in that respect, and we have too little information to show why the backup should have been a lot slower just because you upgraded to build 8041.  I am assuming that the upgrade was from build 5554 of ATIH 2017 and not from an earlier version of the product such as 2016.

Please download the MVP Log Viewer app (link in my signature) and take a look at the logs from before and after the upgrade to see if there is anything shown there that may shed more light on this issue?

That's 368GB of backups on a 512GB drive (assuming about 476GB usable as shown in disk management for a new, unused disk).  I'm assuming both backups live on the drive at the same time?  I'm also assuming that these backups are using the default option to let Acronis create the .tib size so they are a single .tib?  I'm also assuming that there is nothing else on this drive so all of it is usable for backups?  I could be wrong though as you say the disk is less than half used, but at present, if both backups live on the drive at the same time, you're using about 77% of actual capacity, by the time the 2nd backup has completed in full

Let's keep in mind that to create a single backup file, the drive needs continguous space and must seek and find that space as it's writing.  If the drive is empty, the first backup should have no issue since it has free reign of the available space.  However, backup 2 now has to compete with the remaining space on the drive which is more than 2/3 full by the time it's done, making it have to work harder to find the free space for that large, single file in backup #2, which backup #1 didn't have to contend with.  

As the drive fills up, it becomes slower (althought if you have about 100GB free still, it should be reasonably fast, but we don't know how much free space is left now and how much other space is being used for other stuff, so can only assume).

If you want a good, comparitive test, you would need to remove all content of the drive and run a new full again to see if that makes any difference at all as that would be more in line with the oirginal backup that had the full space to work with as well. 

 

Bobbo,

Thanks to the detailed reply, I have a 4TB USB 3.0 where I am backing up the files. Sorry forgot to tell you that, the 512 gig was the laptop drive.

thanks

Steve,

Yes I updated from build 5554 to 8041, I will download the viewer and check it out.

Thanks

Steve,

I downloaded build 8053 and installed it on my laptop. I did a full backup and it took 42 minutes to complete. I don't know it the new build had anything to do with it but I am happy now.

Thanks you and  Boboo for your help.

Could be - hey, it's working, so that's all that matters now.  Hopefully it continues to do the same moving forward.

Sometimes there are local weird things like an underpowered USB port, change in the USB cable of the external drive, switching to a PC back USB port, that have been the culprit for others with backups becoming slow or failing completely.  

On my PC, my front USB ports are underpowered and cut-out at times when there is a long read or write session and a spinning drive involved (even laptop 2.5" spinning drives).  SSD's work without issue on these front ports since they have less power draw.  So, in my case, I need to use the back USB ports which provide more power for spinning drives.  

I also have a crappt 1TB external with a micro usb 3.0 connector.  If the cable is not perfectly straight between the PC and the hard drive, the micro usb side pins don't make good contact with the drive enclosure and the hard drive can lose connectivity from that end.  I won't be buying an external drive that uses a micro usb 3.0 connection ever again!
