So, for example.. /backup/usr - contains identical copy /backup/dailys/usr/Mon - contains files that changed on /usr on Monday. Then just set things up to rotate/expire the old copies and you have an easy way to get files back you deleted that you didn't mean to. I can post the whole script if you're interested... -philip Philip: I would be very interested in seeing your script if you would kindliy post it. Thanks!

backup system rsync - dump
I have two disks; one is the fbsd system drive, the other is for backup purposes. I'm in doubt about what to use: dump or rsync I guess I can do something like: mount /dev/ad1s3a /backup/root mount /dev/ad1s3d /backup/var mount /dev/ad1s3f /backup/usr /usr/local/bin/rsync -avHxS --delete /usr /backup/usr for /usr / and var OR #!/bin/sh newfs /dev/ad0s3a newfs /dev/ad0s3d newfs /dev/ad0s3f mount /dev/ad0s3a /backup/root mount /dev/ad0s3d /backup/var mount /dev/ad0s3f /backup/usr (/sbin/dump -L -0f - /)|(cd /backup/root ; /sbin/restore -rf -) (/sbin/dump -L -0f - /var)|(cd /backup/var ; /sbin/restore -rf -) (/sbin/dump -L -0f - /usr)|(cd /backup/usr ; /sbin/restore -rf -) umount /backup/root umount /backup/var umount /backup/usr tunefs -n enable /dev/ad0s3d tunefs -n enable /dev/ad0s3f This gives me a perfect copy, BUT there is a risk if something goes wrong when I have newfs'd the backup drive.

Re: backup system rsync - dump
I have two disks; one is the fbsd system drive, the other is for backup purposes. I'm in doubt about what to use: dump or rsync I use dump/restore, but do the command slightly differently. Since dump works on a file system I cd to the destination mount point and work from there and I don't have to put the cd in the middle. cd /backup/root dump -0aLf - / | restore -rf - works fine. You don't have to newfs each time, but you do need to do something to clean out the destination file system so I guess newfs works as well as rm -rf. jerry I guess I can do something like: mount /dev/ad1s3a /backup/root mount /dev/ad1s3d /backup/var mount /dev/ad1s3f /backup/usr /usr/local/bin/rsync -avHxS --delete /usr /backup/usr for /usr / and var OR #!/bin/sh newfs /dev/ad0s3a newfs /dev/ad0s3d newfs /dev/ad0s3f mount /dev/ad0s3a /backup/root mount /dev/ad0s3d /backup/var mount /dev/ad0s3f /backup/usr (/sbin/dump -L -0f - /)|(cd /backup/root ; /sbin/restore -rf -) (/sbin/dump -L -0f - /var)|(cd /backup/var ; /sbin/restore -rf -) (/sbin/dump -L -0f - /usr)|(cd /backup/usr ; /sbin/restore -rf -) umount /backup/root umount /backup/var umount /backup/usr tunefs -n enable /dev/ad0s3d tunefs -n enable /dev/ad0s3f This gives me a perfect copy, BUT there is a risk if something goes wrong when I have newfs'd the backup drive.

Re: backup system rsync - dump
I am using rsync for syncing fwo hard disk(with all the files or make it hot backup) and must say rsync is perfect.. It will save you a lot of time.

If you'd like to go down that route (of incremental backups), then consider rdiff-backup, which makes a 'live backup' in the same way that rsync does but also saves the rsync 'transaction log' so you can produce a previous day's image easily, and store the differences compactly - the saving on the network in rsync becomes the saving in disk space for the incremental backups. http://www.nongnu.org/rdiff-backup/ http://www.howtoforge.com/linux_rdiff_backup I've been using this for a few dozen machines with no problems so far.
