The DVD-R or DVD+R, which is best for data backup ?





blueray
Hi, I have done a search of google and found some pages about both DVD-R and DVD+R.
However, it is hard to say which is better than other.
Because of those have almost same specs and only few different on access method.

What do you thing about the above media disks ?

Today only,I know this thing by you.
Nice topic.

But,I don't think these are good for data backup.
Because of its speed,quality,lifetime etc..

Try External SSD flash drive.
It is good for backup.

i've read somewhere DVD+R is better, but DVD-R has more compatibility (which should not be an issue now compare to 10 years ago), so for today, DVD+R should be better.

anyway, DVD is prone to being unreadable just after a year no matter how you store them, so hardisk is still a better bet.

Yeah, and the compatibility issue really only involved the ability to play movies on certain DVD players, so it's not really a problem for backing up files. Most DVD and Bluray drives today are multi-format anyway, so using them will rarely be an issue.

DVDs are a cheap way to make backups, though I will concur with above posts and say that a hard disk is still a better option. In theory, a DVD is supposed to stay readable for 100 years. The oldest ones I have are about 10 years old, and they still work but they were stored in a case. Can't say anything about the long term. But if you're backing up several gigabytes of data, a hard drive is more convenient and versatile anyway.

The right makes of external USB hard drives are pretty hardcore. I used to used a bunch of DVDs and and label them but it just gets well out of hand if they aren't RW. Plus you got to split the files into rars or whatever so it's just massive hassle and time.
