Package: backuppc
Version: 3.2.1-2
Severity: normal
Dear Maintainer,
there is a constant error in my backuppc backups. I think this is
because of the length of the relevant file name, which gets even
longer when escaped by backuppc and hits the 255 character limit of ext3fs.
The file in question is in the opera icon cache, it's called
data%3Aimage%2Fpng,%89PNG%0D%0A%1A%0A%00%00%00%0DIHDR%00%00%00%10%00%00%00%10%08%02%00%00%00%90%91h6%00%00%00%19IDAT(%91c%BCd%AB%C2%40%0A%60%22I%F5%A8%86Q%0DCJ%03%00%DE%B5%01S%07%88%8FG%00%00%00%00IEND%AEB%60%82
According to wc -m, that's 225 bytes long.

(72e2a83d50e324a05f04cceab2827ab1)
backuppc escapes each % as %25, according to wc -m the result is
327 characters.
In my case this doesn't really matter, the opera icon cache isn't
critical, but there seems to be a general problem with backuppc's
strategy of renaming files. backuppc should be able to backup
long file names, up to the filesystem limits. Probably it needs to
store long critical filenames separately.
Here's a message from the backuppc-users list that helped me to
understand the problem:

Hi,
I was going through those very old bugs and decided to close them, as
BackupPC V4 has evolved a lot and a lot of those bugs seems to be
feature requests, unsure if the problems still exist or otherwise not
actionable.
Please feel free to reopen the bugs, if think that is sensible, or
maybe if it as feature request check directly with upstream.
