EaseUs Todo Backup - upgrade or not?

Hi;
I have the home (paid) version 11.5 Todo Backup on Windows 10 - single user license.
Every time I start the program, I am reminded that there is a newer version available, but I have always declined, since the version I have seems to be working fine.

So now, with version 13.0 released, and I'm still running 11.5 on Windows 10 ver 2004, I'm wondering whether maybe it's worth the $14.99 to upgrade to version 13.0.

There is one thing that bothers me about the older ver 11.5 - that is when I do a partition backup, I get a warning that some partitions on my drive cannot be read, and that a sector by sector backup must be performed.
i get this warning because I have dual-boot with Ubuntu 20.05 and Windows 10, with the system booting into Grub.
When I contacted EaseUs, I was assured that the sector by sector backup is safe, but I have never attempted to do a restore, as the system is working fine, and I don't want to chance a failure if it is unnecessary.

If version 13.0 has fixed the issue with Linux (or any other non-Windows partitions), then I would want to go for the upgrade. But if not, I don't think it's worth the $15.

Your advice?
Thanks

I just had a chat with EaseUs, and unfortunately, the new ver 13 does not fix the problem with partition backups on drives with Linux partitions. I would have gone for the 13.0 upgrade if it would have fixed the issue that forces sector by sector backup.
It's not an issue for me, but why should I spend $15 on nothing. Perhaps ver 13.0 offers faster file backups, but I do all of my backups at night and have it shut down the system when it's done, so I don't care how long it takes to complete.
That said, I can always choose to upgrade any time I start the program. They're pretty persistent with reminding me that an upgrade is available.

When version 12 was released, I seem to recall having installed the 30-day trial, but decided not to purchase. I don't see a trial for the home version of ver 13; only the free version, which is so badly stripped, I don't think I would consider it a good representation of what the home version of 13 would be like.
In my chat, I asked, and the agent confirmed that version 11.5 (which I currently have a license for) will continue to work on future versions of Windows. So, until that fails to be the case, I will stick with ver 11.5, and save the $15 for a more necessary upgrade, or for a six-pack of my favorite beer!
