Migrate RAID 1 to 5

[TEMP12345]

Good afternoon, hope someone can help. I have a QNAP TS-464 and I am trying to change from RAID 1 to Raid 5 and whilst the 3rd new disk shows as installed it does not show as disk 3 in the storage pool, and therefore cannot use the option to Migrate Raid Group. I have QTIER enabled and have to RAID Groups, 1 & 2, RAID Group 1 being 2 x M2 SSD, do I need to remove the Ultra-High Speed tier to then allow me to migrate the raid group? Thanks in advance - PS Im not very techie, this NAS malarkay is rather baffling

I have never done a raid level migration on a tiered pool..you might be correct and the tier would need to be removed first

Thanks - its rather confusing, especially when you dont have the foggiest. Dont want to screw it up and lose my data

[dolbyman]

Well you should never fear to lose your data..that's why you do backups

Backups WILL save your files one day..no way around it

[TEMP12345]

Is the snapshot feature, which I have enables, a backup?

[dolbyman]

No .. Snapshots are gone on NAS failure / malware infection (of the NAS)

Only backups are backups (external copies of the files to USB/NAS/cloud/etc)

I have 13tb of data - how do you backup that - need another NAS....lol

[dolbyman]

a 14/16/20/etc TB USB backup disk would be a start

The amount of tears/anger that people have shed when they have lost all their files to malware infections or hardware defects is normally not a laughing matter.
