Ignore a top level folder been used as a share

[DerekChen65535]

Situation:
I have a array of 4 disks as my main storage. 2 ssd pool brtfs RAID1 as cache. And a 4 disk brtfs RAID0 pool as a backup of my main array. I would like to periodically back up my file from my main array to that 4 disk brtfs pool through rsync. Then remove those disks put somewhere safe. The command I am using is:

rsync -av /mnt/user/ /mnt/coldbackup/array_backup/

 

However, unraid will automatically mark "array_backup" as a share then add it under /mnt/user folder. Such behavior will create a recursive loop until the /mnt/coldbackup is full.   

 

Two possible solution I can think of:

 

1. Using tar to compress array to one file. Not only it takes very long time but if the file is corrupted , that back up is useless. 

 

2. Tell rsync to ignore that /mnt/user/array_backup

 

Question:

Just curious if there is a setting to let unraid to ignore a top level folder been used as share. Or mark a disk pool not been used as part of a share?

Probably a better option is to mount that backup pool via Unassigned Devices as UD devices are not part of User Shares.   UD is the way you are expected to handle removable devices.

Can I mount 4 disks as a brtfs array in UD?

AFAIK yes, as soon as you mount one, the rest will mount along with it.
