Rsync wrapper making syncing easy
This program is a wrapper around rsync. It will help you:
if you need to sync files from remote server frequently
No need to keep the location of the file in your mind. It finds them for you.
Python >= 2.6 (Python >= 2.7 for tests)
locate installed with up-to-date database on the remote system
Make sure you have an SSH configuration file in your $HOME directory. This tends to be very useful, as it keeps all necessary logins and ssh server access configurations, e.g.:
Host spameggs Hostname 184.108.40.206 Compression yes CompressionLevel 9 User guido Host example2 HostName example2.examples.com User johndoe Port 22
Syncing ZODB from remote server configured in ~/.ssh/config as spameggs. We choose not the first database, but the second:
$ pwd /home/roman/projects/plone4/var/filestorage $ zyklop spameggs:Data.fs . Use /opt/otherbuildout/var/filestorage/Data.fs? Y(es)/N(o)/A(bort) n Use /opt/buildout/var/filestorage/Data.fs? Y(es)/N(o)/A(bort) y rsync -av -e ssh -l roman -p 522 --partial --progress --compress-level=9 220.127.116.11:/opt/buildout/var/filestorage/Data.fs /home/roman/projects/plone4/var/filestorage
Syncing a directory which ends with blobstorage, and not directories like blobstorage.old from a remote server:
$ pwd /home/roman/projects/plone4/var/blobstorage $ zyklop spameggs:blobstorage$ . Use /opt/buildout/var/blobstorage? Y(es)/N(o)/A(bort) y rsync -av -e ssh -l roman -p 522 --partial --progress --compress-level=9 18.104.22.168:/opt/buildout/var/blobstorage /home/roman/projects/plone4/var/
Use an absolute path if you know exactly where to copy from:
$ zyklop spameggs:/tmp/Data.fs . Use /tmp/blobstorage? Y(es)/N(o)/A(bort) y rsync -av -e ssh -l roman -p 522 --partial --progress --compress-level=9 22.214.171.124:/tmp/Data.fs /home/roman/projects/plone4/var/
Syncing a directory which needs higher privileges. We use the -s argument:
$ zyklop -s spameggs:blobstorage$ . Use /opt/buildout/var/blobstorage? Y(es)/N(o)/A(bort) y rsync -av -e ssh -l roman -p 522 --rsync-path=sudo rsync --partial --progress --compress-level=9 126.96.36.199:/opt/buildout/var/blobstorage /home/roman/projects/plone4/var/
I’m dealing with Zope servers most of my time. Some of them have a huge Data.fs - an object oriented database. I do have in 99% of the cases an older version of the clients database on my PC. Copying the whole database will take me ages. Using rsync and simply downloading a binary patch makes updating my local database a quick thing.
To summarize, with zyklop I’d like to address two things:
Downloading large ZODBs takes a long time and bandwidth. I simply don’t want to wait that long and download that much.
Most of the time I can not remember the exact path where the item to copy is on the remote server.
tty support: sometimes needed if SSH is configured to only allow tty’s to connect.
Don’t hang if only password auth is configured for SSH
If you’re interested in hacking, clone zyklop on github:
Changed host, match parameters: Now you can specify the source host and path match in one parameter delimited by a column, similar to scp (e.g. foohost:/path)
Allow to provide an absolute path to the file you’d like to copy.
Added basic support for using sudo in finding and syncing (rsync)
Added argparse as dependency as Python 2.6 won’t have it
New positional argument to provide destination to copy file/directory
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
