@scottalanmiller Having remote backups in another part of the world (geo-redundant backups) is a solid disaster recovery strategy. It helps protect against data loss from natural disasters, regional outages, or local ransomware attacks. But remote backups are only as secure as the passwords and encryption protecting them.

RE: Decrypting a LUKS encrypted drive at boot
Here is something i found:
- Ensure LUKS Drive is Configured
If the drive isn’t encrypted yet, you can encrypt it with LUKS:
bash
Copy
Edit
sudo cryptsetup luksFormat /dev/sdX
Replace /dev/sdX with the appropriate drive/partition. Be cautious—this step will erase all data on the drive.- Add the Drive to /etc/crypttab
Edit the /etc/crypttab file to configure the system to unlock the drive at boot.
Open the file:
bash
Copy
Edit
sudo nano /etc/crypttab
Add an entry for the encrypted drive:bash
Copy
Edit
cryptname /dev/sdX none luks
cryptname: A name for the decrypted device (used later in /etc/fstab).
/dev/sdX: Path to the encrypted device.
none: Use none for a passphrase prompt at boot or specify a path to a key file.
luks: Indicates LUKS encryption.
Example:bash
Copy
Edit
cryptdrive /dev/sdb1 none luks
3. Add the Decrypted Device to /etc/fstab
To automatically mount the decrypted drive after unlocking:Edit /etc/fstab:
bash
Copy
Edit
sudo nano /etc/fstab
Add an entry for the decrypted drive:bash
Copy
Edit
/dev/mapper/cryptname /mnt/mountpoint ext4 defaults 0 2
Replace:/dev/mapper/cryptname with the mapped device from /etc/crypttab.
/mnt/mountpoint with your desired mount point.
ext4 with your file system type.
4. Generate an Initramfs
If the root file system or a critical drive is encrypted, you’ll need to update the initramfs to include decryption tools.Update the initramfs:
bash
Copy
Edit
sudo update-initramfs -u
Verify that the cryptsetup package is installed in your initramfs configuration.- Test Boot Behavior
Reboot the system and observe the decryption process:
If you specified none in /etc/crypttab, you should be prompted for a passphrase at boot.
If a key file was used, the drive should decrypt automatically.
6. Using a Key File for Automatic Decryption
To avoid entering a passphrase at boot, use a key file:Generate a key file:
bash
Copy
Edit
sudo dd if=/dev/urandom of=/root/luks-keyfile bs=4096 count=1
Set permissions:bash
Copy
Edit
sudo chmod 600 /root/luks-keyfile
Add the key file to the LUKS header:bash
Copy
Edit
sudo cryptsetup luksAddKey /dev/sdX /root/luks-keyfile
Update /etc/crypttab:bash
Copy
Edit
cryptname /dev/sdX /root/luks-keyfile luks
Update the initramfs:bash
Copy
Edit
sudo update-initramfs -u
Reboot to test automatic decryption.- Troubleshooting
Device not found during boot: Ensure the correct device path is used in /etc/crypttab.
Passphrase prompt not appearing: Verify cryptsetup is installed and included in initramfs.
Boot hangs or fails: Boot into a live session, comment out entries in /etc/fstab or /etc/crypttab, and investigate.

Maybe flashing the raid card firmware back to its original state you can see the drives. You can pick up the firmware on dell support and drivers site.

You can also try Chrome remote extensions.

RE: Proxmox: iOS or Android tools
@dbeato Like others have posted they do have web admin portal. I find it so easy to navigate on that portal. Very easy and not so troublesome like some ESXI interfaces.

I do not know if this matters maybe you should look into an FTP that caters between Linux and Macs poossibly.

We have all APCs and they work fine in our DC. They work fine for us which include our windows and linux servers.

Check for driver updates, ensure that your Radeon graphics card has the latest drivers installed. You can download the latest drivers from the manufacturer's website or use an automated driver updater tool.

I don't know if this applies or not. I would be asking for references from current customers if available.
