Guided Replica

Today I installed
‥replica‥(1)
on my VPS. I noticed that I can write some helper scripts around it
and here they are.

You can download them from
[[[ms
.CW https://sirjofri.de/files/guidedreplica .
]]]
[[[ebook
<code>https://sirjofri.de/files/guidedreplica</code>.
]]]

You can install it like that:

[[[ms
.P1
# bind your client $home to /n/rclient
# bind your server $home to /n/rserver
hget https://sirjofri.de/files/guidedreplica/guidedreplica.rc | rc
# follow the prompts
.P2
]]]
[[[ebook
<code><pre>
# bind your client $home to /n/rclient
# bind your server $home to /n/rserver
hget https://sirjofri.de/files/guidedreplica/guidedreplica.rc | rc
# follow the prompts
</pre></code>
]]]

This will also install two helper scripts to
[[[ms
.CW $home/bin/rc/replica/ .
]]]
[[[ebook
<code>$home/bin/rc/replica/</code>.
]]]
Reproto copies one proto over the other. You can choose which one you want to keep.
Reupdate is helpful if there are update-update errors. It should automatically solve them (untested, but should work).

‥‥Update:‥‥
‥replica‥(1)
has issues. Often it does a bad job tracking changes, leaving removed files there and vice versa. I never encountered data loss, only inconsistencies in the copies.

Many people use
‥mkfs‥(8),
which does not overwrite changed files. At some point I will build some scripts around it and use that instead of
‥replica‥(1).
