where Rsync falls down, is if you need a point in time snapshot... Rsync processes one file at a time, so if the files are being updated while its running, the differnet files will be copied at different times. This is usually fine for static archives of files and such, but unsuitable for a

[CentOS] remote backup

Hi list, i've need to backup a partition of ~200GB with a local connection of 8/2 mbps. Tool like bacula, amanda can't help me due to low bandwidth in local server. I'm thinking rsync will be a good choice. What do you think about? Thanks in advance.

Re: [CentOS] Remote backup of server

Hi, you're searching for a solution that makes snapshots with hardlinks 1) use rsync --delete over ssh 2) use cp -al to create generations 3) rotate the generations daily, just with mv The generations use nearly no additional disk space, only changes in the file system consume space (i.e.

Not sure if anyone mentioned this yet, but you might want to have a look at a product called BackupPC, which is based on rsync but puts a really nice front end on it. Not sure if it can work over SSH though. Just read the fine manual to find out. -- “Don't eat anything you've ever seen

Martin, you may want to take a look on http://www.nongnu.org/storebackup/ I am using that program for some month now. It installs easily, runs over SSH connection, and saves a lot of space on the target machine by hard-linking identical files between various backups. on Friday, September 4, 2009

Re: [CentOS] Remote backup of server

Thank you for reply, because rsync is only synchronizing data (with all errors), this is not backup. If on main server will be some data corruption and backup server will connect and synchronize all data with errors, I have nothing :). For example - rdiff-backup is working with increments, so
