Package: rsync
Version: 3.0.7-2
Severity: normal
Hi,
I make local partition backups using rsync, and rsync is the best!
I also run a filesystem meta-data script to validate the backup
partition against its original source.
Since I started using ext4 instead of ext3, the meta-data validation
step now fails because rsync truncates the time fraction to zero on the
destination filesystem.
Here is a simple typescript that illustrates the problem,
$ find srcd -printf '%y %04m %3n %6U %6G %10s %T@ %p\n'
d 0755 2 1001 1001 4096 1312323863.5645407420 srcd
f 0644 1 1001 1001 15 1312307519.8524697750 srcd/s-file
$ rsync -rlptgoDH -x --delete-before srcd/ ddir
$ find srcd -printf '%y %04m %3n %6U %6G %10s %T@ %p\n'
d 0755 2 1001 1001 4096 1312323863.5645407420 srcd
f 0644 1 1001 1001 15 1312307519.8524697750 srcd/s-file
$ find ddir -printf '%y %04m %3n %6U %6G %10s %T@ %p\n'
d 0755 2 1001 1001 4096 1312323863.0000000000 ddir
f 0644 1 1001 1001 15 1312307519.0000000000 ddir/s-file
$ diff -r srcd/ ddir/ ; echo $?
0
As one can see, the contents of srcd/ and ddir/ are identical, however, the
timestamps for all files in ddir/ have had their fractional part set to zero.
Thanks,
Jeffrey Sheinberg

Hello,
to my knowledge rsync is able to use nanoseconds since 3.1.0. So the
issue is fixed in a version released and package for Debian.
Regards,
Christian
