Rsyncing huge file, timeout on rsyncd
Hello,
let me describe my setup.
Source server is debian wheezy, rsync 3.0.9
Destination is qnap TS-410, with rsyncd enabled, rsync 3.0.7
I'm trying to rsync two files, which are exported from source server as iscsi
targets (windows iscsi backups). Files are on btrfs, so I use snapshots during
rsync, so files don't change.
One file is 50GB, second is 550GB in size.
Initial sync over

Behaviour of --append with modified files
We have a rsync'd filesystem which generally contains very large files that only
grow.
We've specifically used the --append option to handle these files - since
otherwise rsync is effectively CPU bound the whole time.
I'd always assumed that any files that were simply modified (without a change in
length) would be handled under the existing rsync logic. However it appears

"Appending" data to the middle of a file using btrfs-specific features
Hello,
I''d like to know if there has been any discussion about adding a new
feature to write (add) data at an offset, but without overwriting
existing data, or re-writing the existing data. Essentially, in-place
addition/removal of data to a file at a place other than the end of
the file.
Some possible use-cases of such a feature would be:

Force delta transfers on rsync?
Is there a way to force rsync to perform delta-transfers even on local
drive-to-drive copies?
The reason I ask is that I've started using a USB flash drive as a
medium for "poor man's off-site backup". Rsync does a beautiful job on
avoiding overwrites of unchanged files, but it would be even better if
it only rewrote the portions of large files that had actually changed

rsync / checksum small block / xfer small block
is there a way to somehow force rsync to check checksum in blocks vs
the whole file and xfer only part that has changed vs the whole file?
for instance i have a few gig file, and it usually keeps adding at the
end, maybe a line a day, yet rsync xfer the whole file over and it
takes forever...

Eliminate the temp copy
Hi,
I have to sync two directories and one is an ftp mount. I had to set a
different tmp dir as tmp files are not allowed in ftp mounts so I see no
point in copying things to a temp dir if they won't be used for the
transfer.
Is there any way to eliminate the use of a tmp dir? If not, could it be
a feature request?
Regards,

Dealing with an unreliable remote
'Lo.
I've run into a frustrating issue when trying to synchronize a
directory hierarchy over a reliable (but slow) connection to an
unreliable remote. Basically, I have the following:

This is a set of nested directories containing binaries and sources for
projects I develop/maintain. Every time a new release is made, I deploy

Comparison of huge files ineffective?
Hi,
how does rsync work if it compares two very huge files on two distinct
hosts (rsync uses a networked connection, via SSH)?
Some observation seems to indicate, that rsync first reads (and
checksums?) the remote (destination) side, then, if finished, it reads
(and checksums?) the local (source) side and then starts transferring
the delta if done with the comparison of these two files on both

retransfer fail of large files with inplace and broken pipe
Hi,
i have to tranfer large files each 5-100 GB (mo-fri) over dsl line.
unfortunately dsl lines are often not very stable and i got a broken pipe error.
(dsl lines are getting a new ip if they are broken or at least after a
reconnect every 24 hours)
i had a script which detect the rsync error and restart the transmission.
this means that if a file has transfered e.g. 80 % i start again from

rsync --append behavior
I am using rsync 2.6.9 in daemon mode under Cygwin, and having trouble
reconciling its --append behavior with that described in the man page:
The man page says that when you use --append, it will update a file by
appending, which presumes the existing data on the receiving side
matches. But when I run rsync with append mode when the existing file
on the receiving side is shorter than on the

The --inplace is very different from the behaviour of --partial when resuming a complex case transfer.
Hi all,
>From the manpage of rsync, I can see the following descriptions:
--inplace
The option implies --partial (since an interrupted transfer does
not delete the file)
So I do the following testings on the `--inplace' and `--partial' for
resuming a file with the following steps:
1- rsync ftp.cn.debian.org::debian/dists/wheezy/main/binary-amd64/

How dangerous is --inplace
Hello list!
How dangerous is acctually the --inplace option if you want to run
rsync to update files that are only read and not written to? What is
the worst that can happen? The file is not readable, the reader gets
half the file of an old version and the rest is from the new version?
There is not a simple way to make it update the file in the standard
way and then change the ownership

There is problem of rsync with options --hard-links --inplace.
There is the problem which I discribed here
https://bugs.centos.org/view.php?id=12820.
rsync does not break hard-link into destination if hard-link has be broken
in source with option inplace.
The problem remains in the latest version of rsync?

--link-dest --inplace updates files without unlinking. What to do?
Hi. This is bug report and simultaneously urgent asking for help. I am trying to write my rsync wrapper script, which will create minutely snapshots of my data using --link-dest. I want this script to be robust, it should work even if I do suspend/hibernate/reboot without notifying the script about this actions, it should work if I make hard-reset of the computer and if I disconnect network.

Hi, I am wondering how rsync-3.0.6 react if it encounters ESTALE error while
synching? If I remember correctly then the rsync-2.6.0 skipping that
file/dir in case of ESTALE error.
