Anti-virus software may be preventing Time Machine from writing to the backup.

This happens on a connected drive. TM to a network drive works just fine. Any ideas.

Antivirus software may interfere with a backup



Though Carbon Copy Cloner is not an Apple Product and Not Time Machine Backup from Apple


There principle remains the same - Get rid of this useless software


Windows-like viruses that self-replicate and affect macOS don’t exist because of the underlying UNIX Foundation and permission limitations.


The macOS operating system resides in a sealed and read-only volume that can’t be opened by users or third-party applications.


This antivirus software only protects the developers’ bank accounts and creates problems for users in return.



Mac app security enhancements are sufficient to protect computers from malware.


Adware and Malware can affect computers and are often downloaded from “shady” websites or developers who inject them into downloads.
