Was looking for insights on how others have setup their volumes?

I have my DNS-323 setup in a straight RAID1 config as my central storage.  All winOS
machines (4 total) store all their user data on the DNS-323.  All the data on my DNS-323
is backed up automatically by my previous NAS (Linkstation Pro) using rsnapshot (daily
for 14 days, weekly for 8 weeks, and monthly for 12 months) to a external USB drive
(connected to the Linkstation Pro).  Software ISOs and Acronis disk images for the winOS
machines are kept on an older KuroBox NAS (w/no backups).

Man, I just could not live with myself, if I lost my digital photos. So I keep copies on my
local deskside computer, the DNS-323, and the Linkstation Pro USB backup disk.  I also make
DVD archives in 4GB increments and, at the end of the year, create another archive on Dual
Layer DVDs (8GB increments).

Personally, I would stay away from D-Link JBOD, because if either disk fails, you lose all you data.

It has been a while... but,

Raid is a lousy backup method. It is mainly used for hot swap business purposes, then there is no down time. A business always has a backup routine accompanying for that capability.

I just broke my raid 1 for the purpose of local backup. I found I did not need a hot fix and had plenty of room. I also do an off-site backup of the incremental.

How did you "break your raid 1"?  (I'm not at that point yet, but I think it would be good to know the steps of converting my raid 1 to two discs)

First RAID is NOT a backup method.
Second RAID & hotswap have nothing to do with one another - hot swap capability is nice to have in a RAID array, but is not a requirement.

RAID is purely about redundancy and the minimizing potential downtime in the event of a disk failure.  RAID without hot swap allows you to defer the down time required to replace the failed disk to a time convenient for you, like outside of business hours.

stillerz - you can break your RAID array by removing one of the disks and formatting the remaining one as a standard volume, when the format is complete, reinstall the disk that you removed and you should have access to the data on it as a separate volume.

Note that should - done this way, you should not lose data, but it's your data, so back it up before you start.

Thanks -- has anyone actually tried that?

[fordem]

Yes - that's why I suggested it.

[stillerz]

Thanks -- that's great.  I was just reading a little too much into the "should", I guess.

The should is there as a disclaimer - it worked for me, I know it's worked for others to whom I have suggested it, and it should work for you - BUT - I offer no guarantees, and I recommend a back up so if for some reason it doesn't work for you, and you didn't backup, I'm not responsible for lost data.

I upgraded with no data loss.  Now, the DNS-323 is strictly a backup, it has no "original" data, so the risk in my case was just the time it would take to copy 800gigs of data back to it if it ate the backup.

[gunrunnerjohn]

I've never heard EXT4 mentioned as being supported, does it actually support EXT4 filesystems?

[gunrunnerjohn]

That one did throw me, I knew of the existence of EXT4, but not in the DNS-323 context.
