similar to: RSync with File Compression

Hello folks! I've been thinking about adding the capability to store files compressed and/or encrypted on either side of the rsync transfer. Let's say there's a storage space provider. I want to store my files on that server compressed (so I don't use more paid space than I need), and encrypted (so they can't read my data). I don't know much about encryption, but I

Hello All, I have been using rsync to backup several filesystems by using Mike Rubel's hard link method (http://www.mikerubel.org/computers/rsync_snapshots/). The problem is, I am backing up a lot of ASCII .log, csv, and .txt files. These files are large and can range anywhere from 1GB to 30GB. I was wondering if on the target side (the backup side), if I can use some sort of compression. I

Hi, Is there a way in which rsync's -z compression (zlib) utility can be benchmarked? I'm trying to compare the compression ratio between rsync and external compression tools like gzip and bzip2. Are there any advantages to using rsync's internal compression mechanism specified with the -z option compared to solely applying external compression i.e. bzip2 to the files and invoking

Hi, I've configured 'backuppc' to transfer files via rsyncd, with enabled checksums. Whith one of the shares I get the error (in syslog): --------------------------------------------------------------------- robbe rsyncd[2183]: ERROR: out of memory in receive_sums [sender] robbe rsyncd[2183]: rsync error: error allocating core memory buffers (code 22) at util2.c(106)

Hi, all - I've been digging into the question of using rsync to sync up compressed data, and read with interest the conversations regarding the rsync friendly patch available for gzip (I belive Rusty provided this patch). For anyone interested, the message thread is archived at http://lists.samba.org/archive/rsync/2002-June/thread.html. The broad outline of this approach were mentioned in

Hi All, I have a 1.8GB PST file that is backed up every night from a cygwin install) and every night rsync transfers about 1.8GB of data for that file. It changes a bit, but for all intents and purposes the entire file is transferred. There are other files on this system that rsync more typically, so I'm fairly certain this isn't a switch or command error on the calling end. I have also

Suppose I have a particular version of a largish compressed archive, most likely a .tgz or .tbz2, and that a remote machine has a newer, and only slightly different, version of the same archive, where most of the content hasn't actually changed much. I might attempt to obtain a copy of the newer archive by first copying my local older copy to the newer name as a file to update from. My

I am the author of BackupPC (http://backuppc.sourceforge.net) and I am working on adding rsync support to BackupPC. I am implementing the server-side in perl, and the client will run vanilla rsync. (BTW, is there the protocol documented? I've answered all my questions by looking at the source, but it would be great to check against any docs.) I started with librsync 0.9.3 and the

Running rsync 2.6.9-1.el4.rf on CentOS 4.4 client and remote server.

Hi folks, Are there any tricks known to let rsync operate on huge tar files? I've got a local tar file (e.g. 2GByte uncompressed) that is rebuilt each night (with just some tiny changes, of course), and I would like to update the remote copies of this file without extracting the tar files into temporary directories. Any ideas? Regards Harri

When I try to start BackupPC with "sudo systemctl restart backuppc" on my CentOS-7 server (running kernel 3.10.0-229.14.1.el7.x86_64) I get the following error in /var/log/BackupPC/LOG 2015-09-26 13:58:14 Reading hosts file 2015-09-26 13:58:14 unix bind() failed: No such file or directory This message occurs in the Perl script /usr/share/BackupPC/bin/BackupPC : my $sockFile

I'd be interested in any corrections or comments on the following instructions (basically for myself): We assume that BackupPC has been installed: sudo yum install BackupPC 1. BackupPC must be run by the user backuppc. Accordingly the lines User apache Group apache in /etc/httpd/conf/httpd.conf should be changed to User backuppc Group backuppc 2. The user backuppc must be able to

For some time now i have been running BackupPC 3.1.0 on CentOS 5.1 x86_64 however after upgrading to CentOS 5.2 BackupPC will not start. "sudo /etc/init.d/backuppc start" return OK but there is no BackupPC processes. This fails also. # sudo -u backuppc /usr/bin/BackupPC -d # echo $? 0 This succeeds, but of course does not fork. # sudo -u backuppc /usr/bin/BackupPC So for some

I have a directory that I backup using rsync with --link-dest and hard links, but I would like the files in that directory to be zipped to conserve space. They are very large log text files (hundreds of megs) that compress 90% or more. Is there some way to do this so that all the files rsync backs up get compressed? The only thing I can think of is manually compressing the directories

I recently moved BackupPC from CentOS-6 to CentOS-7. But when I browse to localhost/BackupPC I'm told Error: Wrong user: my userid is 48[apache], instead of 984(backuppc) As far as I can tell, the BackupPC settings are exactly the same as they were before the move. It seems htttpd is running the program as user apache rather than backuppc, as required. Is there a simple setting in

I finally got BackupPC working under Centos-7.1 after several hours of pain. I had been running it for several years under CentOS-6, and probably CentOS-5, but there seem to me to have been several new issues that arise with CentOS-7. In my experience, the official documentation on this, <http://backuppc.sourceforge.net/faq/BackupPC.html>, is more or less useless unless you have a very long

Can anyone suggest a good open source/free backup software that works on CentOS? I was reading through the manuals on how to back things up and it said do 1 of 2 things. Buy a 3rd party software packages or make one from source. Well I have no clue how to do the 2nd option and I don't want to spend any money so I figured I would as you gurus. BTW I am newb so easier the software the better.
