    i have been using ax64 for a while now and i have noticed that even with around 6 backups created its still only around 48 gig, which is about the same size i would expect for a single image. so my question is when you create a backup with ax64 what type is it ?. is it differential,sequential or a full backup. also is it safe to delete the oldest backup or do i need them all to work (i assume its sequential backup type)

    i cant see any option for setting backup type, compression, encryption etc unless i am missing something

    AX64 Time Machine is primarily a SNAPSHOT tool with INCREMENTAL IMAGING capability. The initial backup is a FULL BASELINE of your protected partition and all others are incremental following that.

    The images are compressed (with no option to change it) so you start out with a reduced compressed image size and eventually with some incrementals it will reach the raw size of the used data in the partition... and grow from there. There is no ENCRYPTION option at this time.

    Deleting the baseline or snapshots OUTSIDE OF THE AX64 TM BROWSER window (Windows Explorer for example) should NEVER be done! If so, the integrity of the backup following the deleted time point will be neutered. Inside of that browser window, all but the most recent snapshot may be deleted. ANy DELETE operation in that window actually performs a MERGE operation which deletes any changes that are no longer relevant to the image and merges relevant changes into the following snapshot (incremental). Even the large BASELINE may be deleted, but the MERGE operation will take some time as most of the baseline is relevant to all images that follow it.

    As with any INCREMENTAL imaging tool, a BASELINE image is required and all relevant changes following that baseline must be retained. In AX64 TM, retention is guaranteed by the MERGE operation (DELETE within the Browser window) when snaps are deleted.

    AFAIK:

    Incremental only.

    Don't delete the oldest backup using Windows Explorer. You can delete it within AX64's Backup Browser.

    Compression not user-selectable.

    No encryption.

    A minor edit...

    "Don't delete ANY backup using Windows Explorer."

    I think it is the other way around: AX64 is primarily an IMAGE based backup software with additional SNAPSHOT capability.

    From the AX64 web site (probably written by ISSO himself):
