    Yes it is fine. The only thing you need to bear in mind, is that any data changes after you start the backup will not be saved.

    When you start a backup wth ATI, it makes an image of how the disk as it is when ATI starts. ATI takes a snapshot of the disk and that's what gets backed up. You can keep working and write to files while ATI is making the backu but the subsequent changes won't be in the backup currently under way. No data is lost -- for example, if you change and save a Word file, the change will be in the saved version of the file. HOwever, that newer version of the word file will not be in the backup since the backup started before you made the change inthe Word file.

    Hello 3xvi4vvtspuiz2s,

    Thank you for choosing Acronis Disk Backup Software.

    Along with other Forum members suggestions and advices would also like to make some comments.

    Please note that due to the Acronis Snapshot technology you are able to continue your work during the backup operation.

    Here is a description of the unique Acronis Snapshot technology:

    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 you have any further questions concerning Acronis software, please feel free to submit a request for technical support or post any of them on this forum. We will certainly try to help you in resolving any issues.

    Thank you.

    Purely out of interest: If a download (of virus definitions, for example) is in progress at the time a snapshot is taken, when the image is subsequently restored will the download continue at the same point in time?

    I don't think the download would be resumed after restore. The AV should automatically update to the latest definition files after a restore on whatever schedule you have set. The restore will not include anything that was added to the drive after the snapshot was taken.

    Hello bulldog356,

    Thank you for choosing Acronis Disk Backup Software.

    Please notice that ususally the data of active processes is stored in memory or paging file, which are not backed up by Acronis True Image. Therefore, after the restore Windows will boot and start all processes as if they were stopped.

    If you have any further questions concerning Acronis software, please feel free to submit a request for technical support or post any of them on this forum. We will certainly try to help you in resolving any issues.

    Thank you.
