Unable to do incremental/differential backup to NAS
I have a Windows 10 laptop that is connected to a Synology DS218+ NAS, and am using Acronis True Image 2018.
I am able to do a complete backup to the NAS. However, whenever I try to do an incremental or differential backup, it accepts the settings (appears to) and starts. When I check for the file on the NAS, it is a new tib file with a full backup label. When I go back into the settings for the backup, the options have been changed back to the full/complete backup. Is there an issue with an incremental backup to a NAS? Any help would be appreciated. Thanks

Thanks very much for the information. Is what you're saying is that going into the backup options and changing something starts a whole new scheme which is initiated with a new full backup? By starting a backup operation, I am committing myself to whatever scheme was saved with the full backup? I need to stay with whatever scheme was saved with the full backup and incremental/differential backups will happen more or less automatically according to the intial settings?
Is my understanding correct regarding this process?
Thanks

Glenn, it is best to decide what type of backup scheme you want to use then stick with that scheme rather than to start changing the scheme type or settings.
See the information provided in the ATI 2018 User Guide section: Full, incremental and differential backups which gives a good overview of how these work.
There is no backup scheme information saved with the backup files themselves, this is purely held within the Windows ATI application settings & configuration data.

If you change settings in an existing backup plan, the next backup created after the change will be always full and all subsequent backups will be created according to the settings specified.

Thanks for confirming the behaviour after backup changes Ekaterina.

Thanks very much for the clarification and guidance. I will let the settings stay where they are and monitor the file sizes of the subsequent backups in the coming week.
Thanks again. The problem had been solved.

So I'm confused here.
I believe I am in a situation similar to the original poster. I had some backup set when I started, and then changed it early last week to do a full backup once a week, and an incremental one daily. That being said, it seems to only have the one full backup TLBX file, which I am inferring it updates daily. I want a large full backup TLB file and then six smaller TLB files. How do I do this?

David, this forum topic was raised for ATI 2018 which does not create .tibx files for normal backups, only .tib files.
If your backup is creating .tibx files, then you have ATI 2020 and the rules have changed with that version for how files are created.
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
