    Can True Image Echo Ent Server build 8076 handle open files ?
    I need to backup my company mailserver each evening and of course the program will be open .
    Also, sometimes I would like to back up our Company data and invariably some files are open on users pc's even if I try to do it at night.

    Hello keevill,

    Thank you for choosing Acronis Remote Server Backup Software.

    We are sorry for delayed response.

    Please notice that Acronis True Image uses snapshot technology which allows backing up of a hard drive in use. Here is a more detailed description:

    Once Acronis True Image initializes the backup process of a volume (which logically corresponds to a single partition, if there are no Dynamic Disks), Acronis Snapshot Manager flushes the file system mounted to that volume temporarily freezing all the operations on the system volume. Immediately thereafter, the Snapshot Manager driver creates a point-in-time view of the system volume and a bitmap describing the used sectors on this volume. Once the bitmap is created, the filter driver unfreezes the I/O operations on the system volume. It generally takes only several seconds to create a point-in-time view of the volume. After that, the operating system continues working as the imaging process is under way.

    Acronis True Image reads the sectors on the system volume according to the created bitmap. Once a sector is read, the appropriate bit in the bitmap is reset. In its turn, the Acronis driver continues working to hold the point-in-time view of the system volume. Whenever the driver sees a writing operation directed at the system volume, it checks whether these sectors are already backed-up, if they are not, the driver saves the data to the sectors that will be overwritten to a special buffer created by the software, then it allows the sectors to be overwritten. Acronis True Image backs up the sectors from the special buffer, so that all the sectors of the point-in-time view of the system volume will be backed up intact. Meanwhile, the operating system continues working and the user will not notice anything unusual in the operating system functionality.

    If we are talking about complex applications such as databases please read the following FAQ article:

    Thank you.
