AX86U Pro as NAS

[ApexRon]

Background:
I had two drives attached to a Raspberry Pi that I used as a NAS. NAS usage is low as it is for archives. The first drive was the active archive and the second as backup to the first. At oh dark thirty every night an automated script would perform the backup. It worked. Alas, the Raspberry Pi died. RiP

Project:
I have relocated drives to AX86U Pro and turned on SMB. Work great. Now I seek your direction for the following:
1. Where can I find a list of commands for the OS?
2. Where can I find information on scripting?
3. Where can I find information for a cron job?
4. I only want one drive visible to a user (admin to see both). How?

Thank you

1. There are hundreds. You really need to be more specific. SSH into the router and press TAB twice.
2. Any online shell scripting guide as well as the Merlin wiki. https://github.com/RMerl/asuswrt-merlin.ng/wiki
3. See the cru command. https://github.com/RMerl/asuswrt-merlin.ng/wiki/Scheduled-tasks-(cron-jobs)
4. The simplest approach would be to use the provided webUI controls to give "No" rights to the specified user. It won't actually hide the top level directory but it will make it inaccessible.

If you're just trying to migrate your backup script it might be quicker if you just post it here for us to look at. I suspect all you need to do is run a cp -a source destination command.

Just what I wanted. Thank you so much.

I have relocated drives to AX86U Pro and turned on SMB.

Standard warning. The router is not an NAS. A router, with its low end processor and limited RAM, is not designed to be an NAS. The USB port and SMB function are addon features mainly to sell routers. I would strongly suggest, if you haven't done so already, to search the subforums to see what issues you potentially may run into if you use the external USB drives for heavy SMB read/write. At the very least you will likely see the RAM spike to 95% to 97% and stay there due to SMB read/write. There are several past thread discussions on high RAM usage with SMB. That excessive RAM usage with SMB is a very common issue with Asus routers and it may cause problems with other services on the router. It may even eventually cause the router to lockup requiring a reboot.

While one can attempt to deal with the SMB high RAM usage by clearing the router's cache, one will find the RAM jumps right back up after a short period of SMB read/write usage. Some have even gone so far as to create a CRON job to clear the cache at scheduled times.
