Hello Community,
I recall encountering an article that explained how Commvault handles files during the 2nd copy process If files/chunks on primary storage infected/compromised by ransomware
it mentioned during aux copy, CV opens the each file including infected files, checks the header, and compares it with its own metadata reference.
If the file has been modified or changed to the extent outside of cv process then CV skip files/chunk during the copy process and that prevent data on the 2nd storage overwritten by those compromised files .
Unfortunately, I'm unable to locate the article now, and I would greatly appreciate confirmation on this matter.
thanks
