But that means you have to concatenate the parts on disk before you can restore the backup. Another option is to use gnu tar (gtar) with the -F and -L options. This will create a multi-volume tar file, that might be easier to restore. Making incremental backups (with the -N or --newer-mtime options of gtar) will also reduce the space needed by subsequent backups. Yet another option would be to replace your CD writer with a DVD writer and write it all in one go, with room to spare. :-) Roland -- R.F.Smith (http://www.xs4all.nl/~rsmith/) Please send e-mail as plain text. public key: http://www.xs4all.nl/~rsmith/pubkey.txt pgpUnAollF2uZ.pgp Description: PGP signature

In addition to other suggestions, for various remote servers I like using rsnapshot (google for its homepage, it's also in the ports collection). It works as rsync over ssh, and it keeps a configurable amount of previous snapshots. e.g. a common configurations is 6 per day at 4-hourly intervals, 7 per week at daily intervals, and 4 per month at weeks intervals, so that you can always go back to see what your files were like up to a month ago. Since your HTML files are probably comparatively small, you may find this method quite convenient. Even for large sets of files the hardlinking of unchanged files means that surprisingly little overhead of disk space is used. -- http://freebsdwiki.org/ - Encrypted mail welcome - keyid 0xBF15490B pgp1EMFTHWZzm.pgp Description: PGP signature

Yeah. This sort of thing is easy to do with a very small shell
script. From your specifications, something like this will do the
job:
#!/bin/sh
PATH=/bin:/usr/bin ; export PATH
htmldir=/usr/local/www/data
recipient="[EMAIL PROTECTED]"
today=$(date +%Y%m%d)
tar -cvjf - ${htmldir} | uuencode backup-${today}.tar.bz2 | \
mail -s "Backup of ${htmldir} on ${today}" ${recipient} \
>>/var/log/backup.log 2>&1
Save that to a file, make it executable and run it out of root's
crontab on a daily basis:
@daily /usr/local/bin/mybackupscript
(be sure you understand the difference between /etc/crontab and
/var/cron/tabs/root, and how to use crontab(1) correctly: do *not*
feed /etc/crontab into the crontab command.)
The recipient should use procmail or similar to feed the backup
messages into uudecode and so extract the compressed tar file.
Cheers,
Matthew

Ah ... a neophyte unwittingly asking to be taught the magic of shell-scripting.
Yes, you can do everything you ask. The trick is to write a shell script to
automate it for you, then add the shell script to cron to be automagically
executed on a schedule.
Here's my suggestion:
1) Study the attached shell script, it backs up to a seperate HDD, but it'll
give you an idea of how things work
2) Read up on "man mail" to learn how to use the mail program from a shell
script
3) Write your own and test it from the command line.
4) Add a cron entry to automate it.
5) Once you're getting good backups, look into using rsync to make the process
even smoother.
#!/bin/sh
# Takes the files in /backup/source and bzips them into an
# archive in /backup/archive
# Also deletes archive files older than a certain amount
DATE=`/bin/date "+%F"`
MAXAGE=14
/usr/bin/tar cyf /backup/archive/backup-${DATE}.tbz /backup/source > /dev/null 2>&1
/usr/bin/find /backup/archive -mtime ${MAXAGE} -delete

backup question
Hi there, We have a large disk that now required 2 tapes to backup. We are trying to use the -M --new-volume-script to execute a script which sends an email to the person and waits for them to press the "c" key to continue. The next-tape scripts works when run from the console directly and the message is displayed to the user to insert the next tape, but tar still reports an error. Have I missed an important step? The tar seems to execute the script but then immediately try to write onto the next tape - before I get a chance to put the new tape in. Any ideas on how to fix this, or a better method of backing up to multi tapes? Here is my script: #!/bin/sh mt -f /dev/st0 rewind tar -c \ -v \ -f /dev/st0 \ --new-volume-script "/etc/scripts/next-tape"\ --multi-volume /backup mt -f /dev/st0 eject and here is the next-tape command #!/bin/sh cat /etc/scripts/newtape.txt | mail -s "new tape" [EMAIL PROTECTED] echo -n Press 'C' to continue while true do read -n 1 keypressed if [ "$keypressed" = 'c' ]; then break; fi if [ "$keypressed" = 'C' ]; then break; fi done cheers craig ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: backup question
Here's how I do it... - Open a writable Samba share on the FreeBSD box. - Map the drive from Windows and ensure the Win-user can write to it. - Schedule Robocopy (Res. Kit utility) to sync the Samba share from publications. Should do it. Robocoy script should be something like: robocopy.exe C:\publications J:\sambashare /mir >> C:\robocopy.log where C:\ is your local source directory that you are syncing from and J: is your mapped Samba share on the FreeBSD box.

drive image dd booting backup question
Hi, I have two identical (model/size/etc.) hard drives in a computer, both of which are recognized by the PC's BIOS, both of which are listed in dmesg as ad0 and ad1, respectively, and both of which appear as /dev/ad0 and /dev/ad1. One is master, one is slave. The slave (ad1) is never mounted. My goal was to install FreeBSD and set up apps for a user on the 'master' drive (ad0), then 'image' the drive over to ad1 (to produce backup media for the project) using the following command: dd if=/dev/ad0 of=/dev/ad1 bs=512 So far, so good, everything works great. dd reports that everything went smoothly. Then I attempt to boot off the that slave drive, after performing the following steps to make what was once ad1 is now the primary ad0 drive: * disengaged the drive data cable from ad0 * set ad1's jumper to a single drive * changed the bios to recognize only one drive When I try to boot off what was once the slave drive (ad1), however, I get errors that /boot/loader and /kernel can't be found. >> FreeBSD/i386 BOOT Default: 0:ad(0,a)/kernel boot: Not ufs No /kernel Does anybody have any thoughts on what I might have missed? Google and newsgroup searches have not produced an answer that's helpful. Of course, I hope I haven't committed some remedial error and wasted your time with this post. Thanks, G.
