I have a question about DVD+RW vs. DVD-RAM. I read through the archives but
I didn't see anything comparing DVD+RW vs DVD-RAM. Here's my plan:
a) DVD+RW or DVD-RAM for incremental daily backups. I am planning on at
least 7 disks so I can extend the lifetime of the media. DVD-RAM would last
longer and I like the hardware verification.
b) DVD+R for archiving weekly and full backups. Probably dual layer for
full backups and single layer for weekly. I don't think I'll generate much
more data than that.
Will DVD+R, DVD+RW, and DVD-RAM all work fine when I need multiple disks for
each task? If a weekly backup needs 3 disks, will that be okay? Similarly
for the other tasks.
Is there any different setup you would recommend? I looked into tape drives
but they are so expensive for the tapes and drives. Right now I'm leaning
towards DVD+RW and DVD+R because I know it's supported according to the
bacula manual.
Has anyone used DVD-RAM with the hardware verification? I'm not sure how to
turn that on/off in Linux since it's just treated as a hard drive.
According to the wikipedia entry, it will take about twice as long to write.
I'm only concerned with backing up a single system (linux 2.6.18) but will
soon be interested in at least 1 more.
Thanks.
