[Bacula-users] DVD+RW vs DVD-RAM for incremental daily backups.
Hi! I read about bacula and went through the manual a while ago and never set anything up. This time I'm going to go through with it. :) I don't mind rereading everything I'd just like to know if I'm starting off on the right path. I have a question about 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 and never have to overwrite a disk I haven't backed up to a weekly rotation. 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 right now running Linux 2.6.18. Thanks! - Take Surveys. Earn Cash.

[Bacula-users] DVD+RW vs DVD-RAM for incremental daily backups
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'm only concerned with backing up a single system (linux 2.6.18) but will soon be interested in at least 1 more. Thanks. - Take Surveys. Earn Cash.

If a weekly backup needs 3 disks, will that be okay? Similarly for the other tasks. You mean, if you can mix the three media types? No. You can mix DVD+R and +RW but DVD-RAM is treated differently. I didn't phrase it properly. I meant can I backup to several disks of the same type for one task? If my daily backup takes 2 DVD+R disks, is that okay? Is there any different setup you would recommend? I looked into tape drives but they are so expensive for the tapes and drives. The have much higher capacity, are more reliable, and more robust... I I'm not sure I would use the capacity though. It's about $8 per disk for a Verbatim double sided DVD-RAM disk (9.4 GB) in a cartridge. Going the tape route would cost far, far more wouldn't it? prefer tape or, if offsite storage and the ability to endlessly add storage count less than speed (and price) disk. I'm not concerned about speed of a tape vs DVD. I am price conscious at this point though. My old (unfortunate) method was a full backup every 6 months with no incremental backups. I'm now looking at using bacula for daily backups and weekly/monthly full backups. I had a tape drive on an older computer and never used it. It's capacity is so small compared to today's hard drives. It seems to me that by the time I would want to replace DVD-RAM disks, I would be ready to upgrade my tape drive to support larger capacity tapes. By the time I'm ready to replace the DVD-RAM disks, I could be buying blu-ray or hd-dvd or whatever is sufficiently cheap at the time. Let me know if any of this is wrong. :) I like the bacula manual as far as setting everything up. It looks clear how all the parts integrated and how to write a config file for each part. What's not clear is what backup media to choose and what kind of backup strategies people use. 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. Right, it takes longer and it's always on. This is not something you can turn on or off, AFAIK. Oh okay thanks. - Take Surveys. Earn Cash.
