Question : VEEAM - using one synthetic full backup forever

I just recently implemented VEEAM's Backup and Replication software to my VMWare ESXi environment.  By default their backup jobs create a synthetic full of your entire VM.  From then on it never creates another full.  It only creates reverse incrementals.  This is perfectly fine assuming your full is valid and NEVER goes bad..  They do have the option for running full backups on specified days which is something I might resort to, however, I'm wanting to get opinions on this...  I do backup the entire VEEAM backup folders to tape once a week... So...  I guess I have a copy of the full on tape, however, let's say I have a full backup that is 4 months old and all copies are bad?!  I do archive my tapes monthly and keep them from 3 years.  I also keep 2 weeks worth of backups on tape and then send the last full of the month to my vault.  Since I'm makin copies of my full backup and archiving them should I assume that is safe?  The claim that they have fail safes to void changes being written to the full and can detect if the full is bad.

You can use custom format 0000000000 for column C (10 zeros) and format 000-0000-000 for column D

The # puts the number if there is a digit, the 0 puts the number if there is a digit, and a 0 if there is none.
