No. I still have them since i began using that scheme in 2010.
Above backup has compression by zisofs and thus produces quite small
sessions.
In the beginning i used BD-R for it, but even the nicest burners refuse
to burn more than about 300 session to them. With BD-RE there is no need
for the drive to maintain an own table-of-content. It sees only one big
track. So the chain of ISO 9660 sessions can get as long as the medium
has capacity.

I recently performed BD-R tests by copying BD-REs of 2010, made by the
GGW-H20L. (That old burner does not accept any contemporary BD-R for
burning but still does bulk BD-RE backups for me with its sensational 2.3x
speed.)
Half of the copied BD-REs later turned out to be unreliable for writing.
So my hope for a big recycling outcome was disappointed.
But before that they all were readable and passed their MD5 content checks.
On the other hand i have BD-RE from 2008 which get overwritten once every
half year.

I'm not sure whether this list takes attachments. So i will try by a
separate mail.
Have a nice day :)
