image backup very very slow

Thread needs solution

Let me explain. I normally do an image backup of my laptop drive to an external usb3 drive. I use the acronis bootable iso downloaded from my account and burned to dvd. [I do not install acronis true image because the laptop is a DAW and benefits from having as few processes running in the background as possible.]
Anyway, Acronis 2018_15470 writes the tib file [~300GB] in around 1hr. Great. However, just tried using Acronis 2020_22510 and after six hours it shows about one tenth progress on the the progress bar. Tried again - same behaviour. After cancelling each time I look in the save location and find a tibx file around 80-100GB which I then deleted. Went back to ATI2018 and it wrote the tib file in an hour no problem.
Is this a known issue? Surely, it should not be so slow. I wondered about the disc not having burned properly but if that was the case then it would not have verified and I doubt it would have actually booted my laptop. Any ideas anyone?
many thanks in anticipation,
Stefan

Stefan, welcome to these public User Forums.

If you are only using the .ISO rescue media downloaded from your Acronis Account, then this will always be using a Linux kernel OS but where the kernel version changes between different versions of ATI.

I would recommend creating the Windows PE version of the rescue media but this will require that you install ATI 2020 in order to do so, plus would further recommend creating this media on a faster USB 3.x stick (2GB up to max 32GB size) to get better performance.

You could also create the Windows PE media as a Survival Kit on your external USB 3 backup drive and use the same drive to both boot from and to back up to.

See KB 61639: Acronis True Image 2019 and 2020: how to create Acronis Survival Kit - for more information on the process.

Also KB 61738: Acronis True Image: Survival Kit disk partition for backups is limited to 2TB on BIOS-booted systems

And Acronis Article:  The Acronis Survival Kit

Note: ATI 2020 will still be slower than your older ATI 2018 when creating backups but should create smaller backup files due to the use of deduplication that has been introduced.

Hi Steve. Thanks for your suggestions. I will have to think about that. Two things come to mind.

1. Surely though the the ATI 2020 should not be soooo slow should it? More than 8hrs compared with 1hr? That seems ridiculous!

2. The Linux kernel has the advantage of being used on any machine. If I wanted to prepare a Windows PE media disc could I do that on a different W10 computer [my office computer] or does it have to be specific to a particular machine?

cheers

Stefan, I have no idea why your backup should be 8 times slower than with the earlier version media, that does not sound correct at all!

The Linux media is probably a little more agnostic in terms of what hardware it works on, but that said, it lacks support for such as NVMe M.2 drives and RAID scenarios etc.

The WinPE media can be created on a different computer and should work fine provided that no specific device drivers are needed.  New drivers can be added to the WinPE media via the builder tool but not to Linux media.

I’m also experiencing slow backups with verification:

  • Full backup last tib 1 TB Total Time: 02:31:46
  • Full backup first base tbix 1 TB Total Time: 03:25:09
  • Full backup second tibx 1 TB Total Time: 07:19:24
  • Full backup third tibx 1.1 TB Total Time: 08:11:37

William, this topic is focusing on using ATI 2020 when booted from rescue media not using it from within Windows.

William,

This is unfortunately expected behavior with the new tibx format used in TI 2020.  The reason is that in your scenario you have a continual backup chain and in such task configurations backup takes longer as each backup file of the chain is processed by TI to create a new backup.

You need to adjust your backup methodology to create smaller backup chains to retain your preferred performance level.
