Incremental backup!
i want to back-up on cd my www -directory. i want to use for this, cd -media. At some intervals i want to make incremental backup and put the result on cd. . i use kde and i want a grafical tool for write cd. . if u have one solution for my problem pls. send me a reply! -- Any help would be greatly appreciated. regards, Carstea Catalin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Incremental backup solution. was: What logs etc do I need tocheckfrequently?
This solution sounds nice, I can even imagine setting up an additional machine (on the same location though) to have a somewhat galvanic isolation between the disks. Only fire, earthquake and a neutronbomb would affect such a backup solution. However, I could use a push in the right direction when it comes to how to configure and what software to use for achieving the incremental backup tasks. Could you hint me in how your system is doing this in a more detailed way?

First, it's actually a Linux system, though there's nothing particularly Linux-specific about it except the device names and the method of spinning down the backup disk after the job. The cornerstone of the solution is the rdiff-backup program (http://rdiff-backup.stanford.edu/ or in ports at /sysutils/rdiff-backup). rdiff-backup is a python script that mirrors one directory to another. It can do incremental backups and it can do them either locally or remotely. It's really a slick piece of software and I'm continually surprised that it doesn't get more publicity. First, there's the (trivial) script /usr/local/sbin/backup-share.sh. This is run by a daily cron job to backup directories on the disk that contain Important Data. Mine is very specific to my system. It is *not* pretty and I plan to overhaul it sometime soon to include error handling and an external config file. #!/bin/bash # script to automatically back up the important stuff on /nfs/share prog=/usr/local/bin/rdiff-backup src=/nfs/share dst=/backup/share budirs=code emu images media music school software text webpage mount /backup for dir in $budirs do $prog $src/$dir $dst/$dir done umount /backup # put backup drive in sleep mode since we won't be needing # it again for the next 24 hours or so hdparm -qY /dev/hdd A note about the last line: it appears that FreeBSD can only spin-down SCSI disks on command. (See camcontrol(8).) The best way to power down IDE disks seems to be just setting a suspend timeout in the power management section of your BIOS. Once the disk is unmounted, FreeBSD won't touch it thereafter and the system should put it in suspend mode automatically. The crontab entry looks like this: # backup selected dirs in /nfs/share @ 0730 daily 30 07 * * * sh /usr/local/sbin/backup-share.sh That's really about it. Like I said before, moving the backup disk to a separate machine would be trivial. If there are any questions, I'd be glad to answer them.
