SOLVED i need to recreate my pool is this a good way to move my files to local storage?

[opi3636]

so i need to transfer all the files from my nas to local storage. if i put all my files in to 1 7z folder then split it too multiple parts ( i dont have enough local storage to fit the whole """"backup"""" on one drive) so i can put it on multiple local drives so when i recrate my pool i can extract all my files and get my files back in place . from 1-10 how much is this a bad idea (1 worst 10 best). if you have a better idea on how to do this please comment them

edit to add more context: currently my setup only have 1x4tb hhd and i want to add a second hhd to run raid1 so i will have data redundancy

The problem is that you only have to get corruption in one file and you lose everything after that.

Basically you need a proper backup, that you can then restore from. Probably better to build another PC/Server, attach disks to that and then replicate to that.

OR

Get a disk shelf and an external HBA. Put new disks in the shelf and attach to the TrueNAS Server. Then internally replicate between pools

sorry some stuff get mixed out i rewrote this post like 2-3 times before posting. currently my setup only have 1x4tb hhd and i want to add a second hhd to run raid1 so i will have a backup and i rad on the internet that i cant add individual drive so i need to recrate my pool with with the 2 drives so i need to format the drives so i want to move my files to local storage while i recrate and configure my pool

run raid1 so i will have a backup

RAID is not a backup.

i rad on the internet that i cant add individual drive so i need to recrate my pool with with the 2 drives

You read incorrectly.

sorry i meant redundancy

and thank you for confirming that i can add an individual drive

@opi3636 as @danb35 indicates. If yu have a single drive in a vdev you can always add another (of the same size or bigger) to the vdev as a mirror (assuming you have a spare SATA port)

Be careful that you add as a mirror. If you add the second drive as a new vdev that you will have a striped pool of two disks and no resiliancy (failure of either vdev will kill the pool). The only way out of that situation is to either destroy the pool OR add 2 more drives, one into each vdev as mirrors.

sorry im really new to using zfs/turenas in general what i want to know is if i extend my current vdev (by going to storage and selecting my drive then clicking extend) can i configure it to run in raid1

...or to remove the freshly-added drive from the pool, and then re-add it as a mirror. These things are possible when you don't have any RAIDZ vdevs in your pool.

You are correct - I forgot that one.
