How configure hdd in new NAS

1st Official Post

    hello friends,

    I'm just building my first serious NAS on the Asrock j4125 platform (the previous one has been running for over 4 years on hp t610). Now I have 3x 3.5 " 3TB and I want to know how to configure them to minimize the risk of data loss and keep disk in max healthy. I do not need super performance, the performance of one disk is sufficient for me. My options:

    1. RAID1 - 3TB array with data protection plus 3TB disk separately. A total of 6TB available.
    2. RAID5 - also 6TB space with data protection.
    3. no raid, one disk for data, the next one for auto-backup the first

    I read on the forum that you don't recommend raid. Why? When one disk fails and when replaced with a new one, the data is not rebuilt?
    On the disk will be movies, music, backups from notebooks and phones.


    All data from the NAS will be backup to the external usb drive WD MyBook.
    Thanks for any comments and suggestions.
    Regards

    I am just reading your post and forum that raid (especially software) is quite troublesome in omv and probably I won't do it.


    How can I solve auto backup for external usb hard drive? Smart socket (for auto-booting disk power) + rsync?

    I wouldn't say that raid is problematic in OMV. If you know how to handle a raid, it doesn't matter if you're on OMV (debian), Ubuntu, or whatever. Problems come when you don't know how to drive. If you set up a raid you have to inform yourself a bit about what you are doing and what problems may arise, to be prepared when they arise.

    The openmediavault-usbbackup plugin is designed for this purpose.

    Unfortunately, I have no experience with RAID, but I have been using omv for several years. I thought this would be the best solution for a few drives. In case of failure of one disk (raid1 or raid5), rebuilding is complicated or rather automatic / template? I know ssh quite well;)

    If that is the case then it is best you stay that way. Almost all home servers do not need RAID of any kind. Repeat to yourself five times a day "RAID is not a backup." In a week or two you will be cured. Take one disk and back it up to a second disk using rsync.

    System Backup Typo alert: Under the Linux section the command should be sudo umount /dev/sda1 NOT sudo unmount /dev/sda1

    Backup Data Disk to Backup Disk on Same Machine: In a Scheduled Job:rsync -av --delete /srv/dev-disk-by-uuid-f8814ed9-9a5c-4e1c-8830-426968c20ea3/ /srv/dev-disk-by-uuid-e67439d5-00a3-4942-bd5f-b84ab86aa850/ Don't forget trailing slashes, and BE CAREFUL. (HT: Getting Started with OMV5)
