BackupPC uses rsync as a transport. Does it use any of rsync's smarts to prevent downloading unchanged files? If I run 2 full backups back to back, does it pull the entire 90 GB both times?
Currently I use this (scripted) and nightly fulls are only 1 GB of traffic (for 90 GB of data) : SRC=20100929-230002 && TGT=20100930-230001 && \ cd /data/backup && \ cp -al $SRC/. $TGT && rsync -avPHxz --bwlimit 500 --delete backup.axzas.com:/data/backup/$TGT/. /data/backup/$TGT/. Is there a way to get BackupPC to do something similar (in that it doesn't download unchanged files). I ask this because I'm importing my existing full backups from the above system and it's taking roughly 10 hours for each full. The data is on LOCAL sata drives, old backups on a mirror, BackupPC data on a RAID 5. BackupPC is reporting speeds of 1.5 to 3 MB / sec. I'd expect speeds closer to 50 MB/sec and I would not expect to pull unchanged files. -- Wayne Walker [email protected] (512) 633-8076 Senior Consultant Solid Constructs, LLC ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ BackupPC-users mailing list [email protected] List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
