Hello everyone, lately,
I have a message (yellow triangle) "All Files Unprotected" only on my cache ssd
So all the files that are on the cache are not protected
How to fix this problem please

Single cache drive has no redundancy. You need a cache pool with more than one disk. Default raid1 is the usual way, best if 2nd drive is same or nearly same size since the mirror will only have the capacity of the smaller of the drives.

I have a 4 TB parity disk
and 3 4TB discs in shares
1 ssd of 500Mo m2 for the cover

the problem is on the files on the cache in "only"
"appdata" example

As was said if you want files on the cache to be protected then you need at least 2 drives as a cache pool in the cache configured as RAID1 (the default for 2 drives) to give redundancy.

 

An alternative strategy is to leave them unprotected but use a plugin like CA backup to make periodic backups to the array.

ok
But in the cache there is also the "System" directory

and "cabackup" only manages a directory and not the disk

Normally system share should only have your docker and libvirt images. libvirt image can be backed up with CA backup and docker image is easily recreated, since it only includes the executable code of your dockers, which are easily reinstalled with the Previous Apps feature on the Apps page.

Hello,

I just put two 4 TB disks in parity as requested and that does not change anything.


I relaunched the "Parity-Check"

The cache is still not protected,


I didn't have that on the old version.

Because you still only have a single drive in cache. Please kindly watch SpaceInvader One basic guides on youtube (or read the Unraid wiki if text is more your thing).

 

Single-drive cache = "not protected" = any data on cache is not protected, including anything still waiting to be moved to the array.

Nobody requested that you have dual parity, we were talking about having 2 disks in the cache pool.

What old version are you talking about? It has been this way for a very long time, but I see you joined the forum before V6. In V5 there was literally no way to have cache protected, since it didn't support multiple disks in cache pool. But it also didn't have anything to warn you of that fact.

 

 

There is no way to have cache protected without multiple disks in cache pool. Either setup cache pool or just make sure you backup anything you consider important in cache and forget about that warning indicator.

In conclusion where I put 2 cache disks or I save the "appdata" directory and I ignore the message.
Sorry for understanding, I go through my friend Google.

 

Thank you for everything and your patience

See the CA Backup plugin on the Apps page.
