I'd like some recommendation on an easy way to make incremental backups. I'm currently looking at rdiff-backup, which is a python script that calls rsync.

http://www.nongnu.org/rdiff-backup/examples.html

It doesn't look too hard to use. But I'm curious to see if there are other solutions.

rdiff-backup seems like a good tool to do it. I used to use the following incremental backup that uses rsync and is written in perl (Ben forwarded it my way):

Code: Select all

#!/usr/bin/perl -w
use strict;

my $host="kamil\@spl64_0";
my $bkuppath="/home/kamil/rsync/backup_new/backup";
my $local="/path_to_backup/";
my $n;
my $N=10;

print("deleting backup.$N ...\n");
system("ssh $host rm -rf $bkuppath.$N");

for($n=$N-1; $n>0; $n--)
{
    print("copying backup.$n ...\n");
    system("ssh $host mv $bkuppath.$n $bkuppath.".($n+1));
}

print("copying backup.current ...\n");
system("ssh $host cp -al $bkuppath.current $bkuppath.1");

print("rsync backup.current ...\n");
system("rsync -vaL -e ssh --delete $local $host:$bkuppath.current");


however I dont bother making incremental backups anymore... I just use rsync for full backups once a week

Code: Select all

rsync -vae ssh --delete /path_to_backup user@spl2:/storage_on_server


if you really want to use a truly incremental approach, then use git, svn or cvs

I use Grsync and tutorial coming up today, took the faster and more reliable. The simulation mode and compression in transition is another feature of rsync. Working quickly, no stalls or crashes. Unison is also good but slow in the index. Moreover, it has not so much that my external hard drive formatted in NTFS. Works well in most cases, however. sbackup is not always reliable tries to run the GUI can both get the app to hang, deamon is sometimes more difficult. But good works, except he did not so much that my external hard drive formatted in NTFS, like Unison.

this is the interesting information about the software modes .
I really like the method and techniques to use this software.

This information is no doubt very useful for new Linux users. Thanks for sharing.

You can use tar for increment backup. But rsync command is better for increment backup.
Example:
rsync -azvr /source/path/ /backup/path/

When you use this command, you don’t need to re-backup every file. It will only backup changed files.

arc script accepts a single file or directory name as a parameter, create a compressed archive file, and the current date embedded into the generated archive file name. For example, if there is a directory called beoserver, you can call the arc script and beoserver directory name passed to the script to create a compressed archive, such as beoserver.20040321-014844.tgz.

I like this system of skipping in the middle of a game. This feature is really beautiful. thank
