split -b (see the man page) - or I think tar has an option to define both 
the 'size of the tape' (in 1k blocks) and a script to run 'between tape 
changes' - so you should be able to sort something out with that...

You could use split(1) as others have suggested. 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. :-)

Sure, have a crontab do the tar daily and then use mutt to send it as an
attachment to the desired email address. Keep in mind, if you're not doing
the mail services yourself, some mail servers limit the file size of
attachments.

There are lots of ways, I'm sure, although, like I said, this strategy
might not be the best option --- I'm no expert.  OTOH, if it works ...
Hmm, something like this in cron?  You'd need to get acquainted
with shar(1), that old sneaky archiving process
tar -R mydir -cf mydir.tar  shar mydir.tar  mydir.tar.shar  mail

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.

begin simple backup shell script
#!/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 21
/usr/bin/find /backup/archive -mtime ${MAXAGE} -delete
end simple backup shell script

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 21

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

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.

 Use mount_smbfs to mount the publications share read-only on the FreeBSD

Re: backup question

2004-02-05 Thread HOLLOW, CHRISTOPHER
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.
HTH,

Christopher Hollow
