[rdiff-backup-users] Debian sarge: OverflowError: long int too large to convert to int

[Marc Fournier]

Hello,

I just came across a problem that I was able to resolve thanks to the
mailing-list archive 
(http://thread.gmane.org/gmane.comp.sysutils.backup.rdiff-backup.general/1633).

The fix seems to be in CVS already. I decided to post here anyway
because it occurs with rdiff-backup 0.13.4 / librsync 0.9.7 / python 2.3.5
(these are the versions shipped with current linux debian stable distribution)
and I thought other people in my case might be happy to find the solution
faster than I did.

The problem happened when I tried to backup from an AMD64
architecture machine on to a i386 one. Some files on the 64bit machine had
timestamps far away in the future (something like 2100) and apparently 32bit
architecture doesn't support this.

So I just changed the date on these files, and everything worked again:
touch /tmp/now
find /path/to/dir -anewer /tmp/now -or -cnewer /tmp/bla  -or -newer /tmp/bla 
-exec touch {} \;

Here is the backtrace (for search engine indexing):
