Acronis True Image and bad sectors on HDD
Hello! I plan to buy Acronis True Image 2019 for creating backup on my home PC. I plan to use incremental backup from main HDD to external HDD. But I wonder what will happen if I will make backup and then after some time my main HDD will gave broken sectors and some files becomes unreadable? What will happen if I will run incremental backup after sectors become bad? Will acronis warning me somehow about that or I will get unreadable files in backup too?
Sorry for my English, it's not my first language and thank everybody for answers!

Steve is correct - multiple backups, time frames and schemes (located in different locations on different media) provide many different opportunities to try and recover from. Industry standard is AT LEAST 3-2-1. Minimum of 3 copies of the data, at least 2 of those are backups and at least 1 of them is stored offsite (or at the very least, different storage mediums).
Once data on a disk is corrupted it's a crap shoot. If a disk starts to fail (bad sectors), the data on those sectors can become corrupted. If they are corrupted on the original source disk, at the time of backup, you're still just backing up the same corrupted data. In some cases, it's not so bad and can be repaired (chkdsk, sfc /scannow, dism OS repair commands). However, in other instances, if you don't have an older copy (archive or previous backup) before the corruption occurred, then you might be out of luck - this goes for any backup tool.
