Job began to write to a used tape, original Data lost?

Hi

Could I ask about a job I just set off. I accidentally had a tape left in the tape drive which was full but I know the overwrite media was set to 4 weeks or so when the tape was originally filled around 2 months ago. 

I started a new backup job today and it began writing to that tape, I cancelled it as I needed to insert a blank tape instead.

Is the data on the original tape now lost or is there a way to recover it?

Backupexec 2012, Server 2008 R2.

Thanks for any info.

A specialist data recovery company might get something back (at a cost, and assuming you were not using encryption, as the format is more or less MTF) however from a Backup Exec point of view that data is lost as soon as the header is overwritten.

Oh and as you stated the tape was full, the backup set that spanned off that tape onto a further tape will have problems - if it was a file system backup then BE should be able to still restore any complete files that reside on the second tape, if it was a VM or database backup then the data within the spanned set that is on the beginning of that second tape is also unusable (although any later, non-spanned, backup sets added to the second tape should be OK)
