Hi, I'm not sure if rsync -H (--hard-link) option is support by BackupPC 2.1.2pl0.
I searched the mailing list via the sourceforge.net mailing list search feature but it isn't the easiest thing in the world to use (no way of sorting results by date). I found a message dated 2004-11-05 from Craig that says: http://sourceforge.net/mailarchive/message.php?msg_id=9976500 > Hardlinks are not currently supported by BackupPC using rsync > XferMethod. Hardlinks are supported by BackupPC using tar > XferMethod. >> Will -H option for rsync help? > Not with the current version of BackupPC. The next version of BackupPC > will support hardlinks with rsync. Most of the code for this is already > in CVS, but it depends upon a new version of File::RsyncP that I haven"t > yet released. The following are BackupPC versions and their release date per http://backuppc.sourceforge.net/ BackupPC 2.1.2 released 2005-09-10 BackupPC 2.1.0 released 2004-06-21 BackupPC 2.0.2 released 2003-10-08 So, since 2.1.2 was released after the above posting from Craig, is that "the next version of BackupPC" that he mentions? I found a message from Paul dated 2005-08-18 that leads me to believe that rsync and hardlinks are now supported: http://sourceforge.net/mailarchive/message.php?msg_id=12681941 > for some reason i had it in my head that backuppc plus rsync plus > hardlinks didn't play well together. (i know all about the > repository copying issues -- that's not it.) looking at > conf/config.pl, can i just add "--hard-links" to > $Conf{RsyncArgs}, and have it all work the way i want? maybe > there was a problem on an earlier release of backuppc? hmmm... But then I found the following message dated 2006-01-01 from Paul: http://sourceforge.net/mailarchive/message.php?msg_id=14339973 > i know i say this everytime this topic comes up, so i apologize in > advance, but until the next release of backuppc with a built-in rsync > client is released (as i understand it), the rsync method does not > preserve hard links. Please, can someone clear this issue up for me? The reason it concerns my setup is that I have 5 servers that I'm backing up. 2 of the servers have a large amount of hardlinks (webservers with a chroot environment for each domain) and although the entire disk space used on these servers is 50GB, the BackupPC backups take over 24 hours to finish. In the "Host Summary" webpage of my BackupPC server it says that the backup size is about 300GB for each of these 2 servers. The MB/sec is in line with the other servers which are about the same size regarding disk space. The others servers backup in about 4 hours. But these 2 servers take much longer to backup because I think rsync is sending each hardlinked file to the BackupPC server as if it were a distinct file instead of just sending the first instance of the file and creating a hardlink on the BackupPC. I want to do daily backup of these servers but if they take over 24 hours to do a backup, I'm going to be doing backups continuously and still not have daily backups. Backups also affect client server performance and I don't want these backups running all the time, every day. I think a 4 hour backup window is reasonable and that if the servers are a little slower during that time, that is fine. Thank you in advance for anyone that can shed some light regarding this topic.
