I recently bought my first pack of rewritable DVDs (+RW). I am going to use them for backup snapshots. Each disc should be able to hold about a dozen snapshots for my needs. I want to get the best wear-leveling possible, so I need to be able to write at different times (not all at once) for each snapshot.
This is the first time I've needed to do this with a DVD. Before, with CDs I would just use ISO multisession. But it seems like for DVD, a UDF packet-write setup is preferred. Since these are backups I don't really need the flexibility of packet-writing. As far as I can tell there is no UDF multisession.
Is there really a distinct advantage to UDF or should I just keep using the ISO multisession?
