ISE Restore Stuck

[KiloBravo]

I'm trying to restore a backup from another (older) server to this newer one, both servers on the same version/patch.

The restore seems to get stuck at 20% for no obvious reason. It's been there for about 3 hours now but on the first attempt it was left for days with no progress. This is being done on the CLI.

ade.log and ise-psc.log do not show anything useful. 

This is 2.7 patch 4.

Any ideas would be appreciated 

[REMOVED]/admin# show restore status
%% Configuration restore status
%% ----------------------------
% backup name: [REMOVED].tar.gpg
% repository: [REMOVED]
% start date: Mon Oct 4 13:45:33 UTC 2021
% scheduled: no
% triggered from: CLI
% host:
% status: Restore is in progress
% progress %: 20
% progress message: Retrieving backup file from Repository

%% Operation restore status
%% ------------------------
% No data found. Try 'show restore history' or ISE operation audit report
[REMOVED]/admin#

First, for the repository where the backup is being retrieved from, can you do a "show repo <repo>" and see the files?  It seems to be timing out while copying from the repo.  I'd also check the directory structure and ensure that the file is there.

thanks for you're reply ComputerRick. I did a show repo and all the files in the directory are showing fine, including the backupfile.

Hi @KiloBravo ,

 please try the restore via CLI:

ise/admin# restore CONFIG-DATA-<xxxx>.tar.gpg repository <repo name> encryption-key plain <password>

the process should look like this:

% Warning: Do not use Ctrl-C or close this terminal window until the restore completes.
Initiating restore. Please wait...
% restore in progress: Starting Restore...10% completed

Hope this helps !!!

Thanks Marcelo. I'm already doing it from the CLI though. Might be worth adding also that this is a restore onto a new server rather than the same server the backup was taken on. I'll edit the original post to include that.

First, I'll put the backup and restore directions below for ISE 2.7.  I suggest you look at the caveats.

https://www.cisco.com/c/en/us/td/docs/security/ise/2-7/admin_guide/b_ise_27_admin_guide/b_ISE_admin_27_maintain_monitor.html#ID312

What is the status of the node that you're restoring on?

Is it in standalone mode?  Fully configured?

Is it a node in a deployment with other ISE nodes?

From the CLI, can you run "show disk" and make sure there's enough space for the backup?

20% is typically a failure to copy the backup to the local disk.  Normally if the key is wrong, it'll tell you that, so I suspect that this is failing prior to or during the copy.
