 |
|
Hi,
we would like to try rdiff-backup for our two fileservers.
Both servers are running debian 3.1 and rdiff-backup 0.13.4.
The filesystem is xfs and we are using ACLs.
The idea is to backup the data of one server to the raid of the other one.
Has anyone experience with ca. 1TB of files?
A test showed that rdiff-backup can't handle our ACLs. Any suggestions?

you need to "apt-get install python-pylibacl"... you can also throw in
python-pyxattr if you want extended attributes.
i maintain a relatively recent 0.13.x cvs snapshot .deb for myself at
<http://arctic.org/~dean/debian/> ... my package "Recommends:
python-pylibacl, python-pyxattr", i should communicate this to the debian
folks at some point.

the overall repository size is not going to get you, just the size of
the largest files and the length of the paths. see recent posts and the
man page for some bugs.
Aside from that you should be fine.
I would be interested in your initial backup stats

I've only found the limit of 235 chars per file name (or directory name)
in the man page.
(But the maximum I've found in my test are 34 appended chars. So it
might be only 221 chars that work.)
That would be OK.
The 2GB per file limit would also be OK, but we have the 2.3 version.
