use Google Translate

    Symptoms

    Backup or a different operation (replication, recovery, etc) fails with the following error:

    The archive is invalid or its type is unsupported

    Cause

    There are several possible causes for this error: either archive metadata is missing or damaged, or  the backup archive itself is corrupted.

    Solution

    First, check if archive metadata is missing or damaged. Solution depends on what type of backup format you use:

     

    If the first slice or xml meta file is available on storage, but backup still fails with the same error message, validate the archive.

    Both Version 11 and Version 12 backup format:

    Validate the archive: see product documentation for instructions.

    If result of validation reports that archive is corrupted, follow the steps below to pinpoint the cause of corruption:

    Troubleshooting

    1. Test the memory on the Agent and on machine with Acronis Storage Node if it is used. See Testing Computer Memory. If memtest reveals any errors with RAM, the backup corruption is due to hardware problems and RAM should be replaced to solve the issue. 
    2. If memtest did not reveal any errors with RAM, and backup is not stored on the internal disk, reattempt the same backup and the same operation on internal disk and check if the issue reproduces. If backup on internal drive does not produce such error, then the data gets corrupt during transfer to external location. Depending on the backup destination, the corruption may be caused by network problems, disk errors on destination, hardware problems with destination, obsolete drivers etc
    3. If the error reproduces when saving backup to internal drive, then the issue requires investigation. Collect the diagnostic information described below and contact Acronis Customer Central

    1. Collect Process Monitor Log while reproducing the issue
    2. Acronis System information from the affected machine
