    I have a subclient which writes the Veeam backup files directly to tape.

    The size of a full backup for this subclient comes around 3 TB.  However, if there are any errors which stops the full backup job in a pending state like network, scratch tape shortage or any need for manually suspending the job will lead to start the existing job from the beginning. Is there a way to resume the backup job from where it was interrupted?

    Hi Genesh, what agent are you using to backup the data, File System iDA?

    Typically the FS iDA should resume from the last successful chunk I believe.  Or are you saying the entire 3TB backup is 1 file, if thats the case then thats expected, unless you can break down the 3TB file into multiple chunks which would be easier to do.

    Also keep in mind, if it fails on tape, the failed chunks (space on tape) can't be recovered until the entire job ages, just a side note.

    Thanks Ali, information about tape space was something new for me.

    Hi Genesh, 

    If you are on the lines that Ali mentioned, that is, using File System IDA and have one (or few) very big files, then, yes, we are bringing out an enhancement in V11 SP14 that would be of help to you. Basically, by breaking up a file into 'extents', and backing them up independently over potentially multiple streams, we are facilitating faster backups, and more importantly here, ensuring that the job  restart granularity is at a sub-file level. 

    Feel free to reach out to me whener you plan to upgrade to SP14 or higher, and want to try out this enhancement.
