I've have in the past used the free AutoVer software to keep a backup of every file modification and newly created file for when our daily incremental backups just don't get the job done i.e. created and deleted between backup windows. However I don't believe AutoVer isn't suited to large data areas that get accessed and modified at the volumes ours currently do. My question is does anyone know of any software that can do this preferably Open-Source and/or free but mostly reliable?
