Package: rsync
Version: 3.1.1-3
Severity: important
Dear Maintainer,
we use the following rsync call to create a daily incremental backup of
our servers:
rsync --delete --stats --numeric-ids -a -H -A -X
-e 'ssh -o BatchMode=yes'
--exclude-from=/some/file
--partial-dir=/mnt/.rsync-partial
--link-dest=/mnt/2015-09-14
10.0.0.99:/ /mnt/partial/
There is a Samba daemon running with "store dos attributes" = yes which
is needed to store the system/hidden attributes of Windows "desktop.ini"
files and creates the following xattrs:
# file: /home/test.user/test.txt
user.DOSATTRIB=0sMHgyMAAAAwADAAAAEQAAACAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAANzEdfAI79ABAAAAAAAAAAA=
One of our servers has 6M files with a complete size of 1.6 TB.
Without the -X option the rsync call takes about 1 hour,
with the -X option it takes 10 hours!!
Over the last year the rsync call took more and more time while Samba
was adding new xattrs.
The sending server has exactly 100% cpu load while running rsync while
the receiving server has only about 40%.
The problem appears with rsync 3.0.9-4 (wheezy) and 3.1.1-3 (squeeze).
Maybe this bug report from 2008 is related:
