A still better option is to use an online backup service such as crashplan or spideroak, as that way your backups are also safe from fire or theft. Also most will automatically create incremental backups several times per hour, so that you can access old versions of your file easily. Crashplan has a free online backup service where you backup to a friend's computer over the internet instead of to their servers. Another cheap alternative for small and very important files is to email them to your google mail account so you can retrieve lost files from any computer. I know of one Comp Sci professor who advises all his students to use that email method of backup for important thesis and suchlike as well as any other backup method. His argument is that if a student's room mate gets arrested, then the cops are likely to take away all computers and backup media, so in that case an online backup will be the only usable one. -- David Pottage Error compiling committee.c To many arguments to function. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
