Linux – mdadm raid recovery and questions – super user

I’ve been working through this in my head for the entire day, and wanted to branch out and get some feedback/opinions on this setup, and how I can handle it if it ever happens to fail. I have a Ubuntu Server system in which the filesystem lives on a relatively small disk by itself, and the main data that it stores sits on 5 disks configured in RAID5 using MDADM. The data that is stored in the RAID array is medium priority. Data recovery jakarta There doesn’t exist any sensitive personal user data, so a loss wouldn’t mean the end of the world.

So, if a drive in the array fails, I can potentially replace it before anything catastrophic happens. Data recovery raw If another drive fails while the first is being replaced, then I just got struck by a bolt of unlucky lighting. What I’m wondering about is what I can do with the drive that contains the OS. Database library Right now, what I’m doing is using rsync to back up the data to a remote location once a night. Data recovery ssd And once a week, that remote location tars the filesystem up, and stores it (it will always keep 4 of the newest tarballs). Data recovery on iphone My logic is that this results in the lowest traffic between boxes, which is good since the server resides at my house, and yet I’ll have sort of “full” weekly backups on the remote end as well as a nightly backup. A data recovery tool The rsync line in my backup script is as follows: rsync –info=progress2 –numeric-ids -aAXPve ssh /* :~/server_backup –exclude=~/Download/* –exclude=/dev/* –exclude=/proc/* –exclude=/sys/* –exclude=/tmp/* –exclude=/run/* –exclude=/mnt/* –exclude=/media/* –exclude=/lost+found –delete Anyway, I’ve encountered drives failing on the RAID array. Data recovery expert It’s easy, and feels satisfying knowing that all you have to do is swap it out, tell MDADM that you replaced the drive, and wait a day or two for the new drive to be completely added to the array. Data recovery jobs I’ve yet to encounter the filesystem drive failing, however. Database concepts 6th edition Which is why I’m here trying to get opinions/feedback on what I should do. I considered adding another small drive for the OS, and mirroring the two using RAID 1. Database kernel The upside, I guess, is that if one drive completely shits the bed, the other will save my filsystem. Raid 5 data recovery software The downside is that if there’s some sort of corruption, or I really really mess something up, the data is immediately mirrored between both devices. Data recovery pro Basically I like the idea of having incremental and full backups more than a mirrored setup for the filesystem. Was it on the OS drive? Did it make it to my remote repository that holds the incremental backups via rsync? Does it solely reside in the superblock on the RAID drives themselves? If I go and get a new drive for the filesystem, install Ubuntu, and add it back into my server, what will it see? Will it see the array at all? I want to be prepared for when this drive finally dies. Data recovery tools mac I’ve been diligent in doing rsync off-site backups, but I want to know for sure if all of what I’ve been doing is a huge waste of time, and what I can do to assure I can continue using my system after a catastrophic failure of the drive that holds the filesystem.
