Consider I already have 2 backups done on a daily basis (let me call them
A and B chronologically -- thus B is the current mirror).
I run 'rdiff-backup --compare' just before backing up : it returns "no
changes"
I run the back up and here rdiff-backup finds thousand of files that have
changed (viewed from session statistics) !!!
This backup is called C and is the new mirror.
When I look at the file statistics, a lot of files are marked as changed.
The first weird thing here is that IncrementSize is not null while
SourceSize and MirrorSize are identical (IncrementSize is always a small
number -<128 -).
For example : home/USER/.kde/share/config/katerc 1 67 67 66
By any chance are these all files with multiple hard links, and if so, does
this excerpt from the rdiff-backup manpage shed any light:
--no-compare-inode
This option prevents rdiff-backup from flagging a hardlinked file
as changed when its device number and/or inode changes. This
option is useful in situations where the source filesystem lacks
persistent device and/or inode numbering. For example, network
filesystems may have mount-to-mount differences in their device
number (but possibly stable inode numbers); USB/1394 devices may
come up at different device numbers each remount (but would gener-
ally have same inode number); and there are filesystems which don’t
even have the same inode numbers from use to use. Without the
option rdiff-backup may generate unnecessary numbers of tiny diff
files.
