Heard that.

I'd set up a post-commit hook on the production system. Have it SSH to
your backup system and do a pull automatically whenever you commit a change.
I made an example project to try it:
me% mkdir example
me% cd example
me% git init
Test file:
me% date > testing
me% git add testing
me% git commit -m 'Testing a new file"
me% git log

Here's a test script to connect from my backup system ("bkup") and simulate
pulling my working repo. I have an SSH public/private key set up for
passwordless login:
me% cat try
#!/bin/sh
export PATH=/usr/local/bin:/bin:/usr/bin
ssh -q -c aes128-...@openssh.com -i $HOME/.ssh/bkup_ed25519 \
bkup "logger -t autopull git pull whatever"
exit 0
Here's the remote system log when I run this from the command line:
me@bkup% tail -1 /var/log/messages
Aug 22 00:24:44 bkup autopull[60592]: git pull whatever
I copied the test script ("try") to .git/hooks/post-commit and ran a commit:
me% git add try
me% date; git commit -m 'Added hook'
Tue Aug 22 00:31:27 EDT 2023
[master 42cb917] Added hook
1 file changed, 6 insertions(+)
create mode 100755 try
me% git log
42cb917 2023-08-22 00:31:27 -0400 vogelke - Added hook
d5fe2ce 2023-08-22 00:09:21 -0400 vogelke - Testing a new file
Here's the system log on the remote system showing my hook ran when the
commit was done:
me@bkup% tail -1 /var/log/messages
Aug 22 00:31:27 bkup autopull[80162]: git pull whatever
Replace the "logger ..." part of post-commit to run "git pull" or whatever.
Hope this helps.
