Hi, Can anyone reassure that files & folders made available to windows via vfs shadow_copy2 cannot be modified in any way? My NAS backups are stored on an iscsi target formatted with ext4 & I'm concerned that they could be tampered with by a virus such as Cryptolocker. Thanks
Should I have mentioned that the NAS backups are snapshots that are made available to Windows clients?
