Hello, All! My question is that when we save a backup of our documents, libraries and desktop etc on same PC but on different drive (in Windows 7), so can any virus, trojan or worm can change or delete any file from that back up? Because files saved in Zipped Compressed Folder cannot be deleted by any exploit. Am I right? Another thing is that some worms like win32/chirr.B not only damage Windows files but they also delete some other secret data like any saved software .exe file, .doc and so on. So at the end, please tell me if this type of worm comes in PC then would it delete Windows 7 Backup files? Can I restore all files from that backup after restoring? Hope for the good answer. Regards,
A virus can always delete any files (backup, compressed or other doesn't matter) on any internal or external drive connected to your pc. You only made a real backup, if you put it on an external drive and disconnect it from pc and power (if lightning strikes your pc and your external harddisk both are dead, if they are connected to power). Long story short: A virus can delete backups. If you store them away from your pc, they're safe.
Thanks! herrkarl Another question about backup in Windows 7 is that I did a backup yesterday, Windows not only saved data in libraries but it also backed up some files of already installed softwares from "Program Files" (which is included in System Drive C but when I restored a software for experiment (after uninstalled), unfortunately Windows didn't back it up and gave a message "Some system files were skipped because they cannot restored to origional location. To restore these files, try a different location". So what does it mean? Can we not restore installed software? Also what's different between System Image and Windows backup? Regards,
