Full backups have slowed down!

Thread needs solution

I have 2 Dell XPS PCs running a fully updated copy of Windows 10 (Home).

Yesterday I updated ATI-2020 to version 38530.  Since I have less than 75GB of data to backup on each system, I run a full backup twice daily at 0800 and 1400.  Before 38530 this backup took about 6-1/2 minutes.  Now with the same amount of data it takes 10-1/2 minutes.  Interestingly enough, if I run a manual backup with 38530 it takes 6-1/2 minutes.  This large discrepancy occurs on both systems.  So why is there such a huge different between timed and manual backups with the updated ATI-2020?

Thanks, Bill

Bill, the first point here is that build 35860 is not ATI 2020 but is ATI 2021.  As such there are differences in the applications which could possibly account for some differences in timing.

There have been no further backups for ATI 2020 since #25700 and the version has been out of support since September 2020.

Bill, an apology / correction to my earlier reply, I wasn't aware that Acronis had released a new build for ATI 2020 just 2 days ago - they normally put a new sticky topic in the Forum when doing so, so you were correct stating you have build #38530.

At this point I have no explanation for you seeing any slower performance for your backups!

Hello Steve,  Thanks for your input.  FWIW, I find this extended backup time to be a big irritation!  Because of this I'd like to go back to 25700.  Where can I find this version of 2020 and can it safely be installed onto 38530?  Thanks!

Bill, you should still be able to download the older version of ATI 2020 from your Acronis Account but in order to install this, you will need to uninstall the later version first.

If uninstalling, then use the option at the bottom of the Settings page to export your current backup task configuration data to a zip file, then you can import this after doing the reinstall.

Done, except I forgot to save my configuration!  But this was no problem to set up again.  Note the following file list which was made after setting up the full backup parameters:

2 questions - why has the new backup lost most of its title and how come the size of the backup has been reduced by 5.5 GB?

FWIW, I compared my backup selection to my other PC and all is the same.  My guess is that the Acronis install came up with a different exclusion list, but I'm not sure about this/

Thanks, Bill

 

Bill, your files list is showing two different backup file formats.

The top file using the .tibx file format is how ATI 2020 and later now create Disk backups.

The other files using _full_ and .tib file format, is a carry over from ATI 2019 and earlier versions for all backup types.

The 5.5GB difference in file size may be related to a difference in default Exclusions or else may be down to the differences between the old and new file formats!

See the following KB documents published by Acronis with regards to .tibx files.

KB 63518: Acronis True Image 2020: do not delete first tibx file

KB 63227: Acronis True Image: Do not delete .TIB or .TIBX files outside of Acronis True Image

KB 63444: Acronis True Image 2020: tibx backups in local destinations

Interesting!  I think I will also uninstall 38530 from my other PC without saving the configuration, :)

BTW, my 0800 backup is running now and I see that it attached "-0001" to the filename.

Note in my file list for the 0800 backup on the 17th took almost double the time of the backup from the previous day at the same time.

Thanks for the superior support!

I've had a similar experience on my home system.

Would be great to find a solution

I really didn't see a big difference on my Dell XPS Home either, but my times are not large so I never looked?

Checked today,

1/29 - 2hrs, 23min, 236GB backup file

2/19 - 2hrs, 11min, 235GB backup file

2/26 - 2hrs, 13min, 237GB backup file

C: is an SSD, other drive being backed up, standard SATA 3 disk, and External USB 3.0 drive is backup drive.

PC was more than likely in use at those times.

However, my wife's PC, completely different story.

Win10 Pro, C: is an SSD, other 2 drives being backed up, standard SATA 3 disk, and External USB 3.0 drive is backup drive.

Now on 1/21, her backup drive was replaced. It died basically. It was a WD My Book 4TB drive, that was a replacement (actually was replaced under warranty with a refurbished unit as it has a white box, replacement this time was in a Retail box). We got a new one before sending the failed one for a replacement under Warranty (less than 2 years into a 3 year warranty).

We were amazed on how FAST it backed up her PC. Normal back-up file size, 550GB +/-. Time on the OLD drive, about 11 hours. New drive installed on 1/21 and it took less than 9 hours! I suspect the old drive has some issues, and might have been running at USB 2.0 speed? Anyway, here job kicks off @ 10AM once a week. Her BACKUP folder:

Again, FULL back-up of 3 drives. 9 1/2 to 10 1/2 hours up until 2/17 when the 38530 was updated, as the 25th almost 6 hours longer.

Running today, and it seemed to take about 2 hours 'calculating' what to backup. Speed during the back-up is 70 - 100Mbps it seems.

Until version 38530 since her back-up was about 2X mine, and assuming more time to gather what had to be backed up, 9 hours was reasonable, which also verified the old drive might have had problems. Now, were at almost 15 hours? Something seems to have changed to me?
