Hei! I apologise, that i bother you with questions, that are not entirely Debian specific. I don't know any better place to ask those questions. If someone here could point a newbie like me to right direction, it would be very much appreciated.
I have a task to set up a file server. I have very small budget but quite high demands for data integrity. I must do everything possible to ensure, that i can recover data after hardware or user failures. The performance of the computer is not very important. There is no way i could buy expensive hardware (SCSI and tape drives are really not an option). I think i can afford two or three IDE disks. So here is my plan. I buy two smaller (and cheaper) IDE disks and use them in RAID-1 array. I hope that this gives me good protection against hardware failures. If one disk fails, then other will still have my data intact, right? The main question is, that how good is the software RAID, when one drive is not lost completely, but it starts to have more and more bad blocks? Will the RAID-1 protect me from data corruption in that case? Any comments? I know, i still have to take backups, because the RAID and mirroring won't protect me against other types of failures. I was thinking about using a separate much bigger IDE disk for backups. If the backup drive would be 7 times bigger than those smaller disks, then i could take a full backup every weekday and have seven copies of my data, every copy taken in different time. This gives me maximum one week to react to data loss or corruption and if i accidently deleted wrong files, i would could restore them from backup, that is not older than 24 hours. So what do you think, is my plan plain stupid, or does this really give me some protection against data loss. Should i investigate any other technologies? EVMS? A bit worried, but still hopeful -- Juhan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
