Henry,
Something to consider. If the purpose is to have a backup in case of
disaster recovery, you should really consider off site, not to a local
USB stick. Also if you are providing support services to clients there
is nothing worse then a system failure and no current backups for
recovery. I don't have remote client voip installations this but what I
do have is my own business servers at a colo that require backup.
What we do is have each server do it's backup locally, then after the
backup we utilize sftp and rsync to move any directories we want backed
up to be copied to a remote backup server. So if anything this could be
an added level of service you can provide to your clients! Extra revenue?
You can implement this a few ways, but here is a link which gives a good
explanation on doing it for a web site a mysql server.

Another option is to use jungle disk, look here

Just some ideas!

Henry,
The quick answer on where to find mounted filesystems is "df" (which
as the man page states "report file system disk space usage").
Here's what a trixbox system reports:
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda2 74842944 2522460 68457256 4% /
/dev/hda1 101086 11084 84783 12% /boot
tmpfs 253700 0 253700 0% /dev/shm
/dev/sda1 2002892 627960 1374932 32% /mnt/usb
The first column reports the device (on this system the USB stick is
/dev/sda1) and the last column ("Mounted on") shows the place where
the device is mounted onto the filesystem (in this case /mnt/usb).
As for redirecting the output of the backup (assuming you can't tell
the backup utility to change where it puts the backup) is to change
the target directory of the mount command, or put in a symbolic link.
The freepbx backup/restore utility seems to create the backups under
/var/lib/asterisk/backups, then creates a directory corresponding to
the backup name, and puts the actual backup file in that directory.
For the mount point idea, instead of mounting to /mnt/usb, you could do
mount /dev/sda1 /var/lib/asterisk/backups
This will hide any files and directories in that backups directory,
and replace them with the directory structure on the USB drive. When
you umount the USB stick they will re-appear.
You can also use a symbolic link:
ln -s /mnt/usb/daily /var/lib/asterisk/backups/daily
This command creates a link in the backups directory called daily,
that then points to a directory on the USB drive. When you backup
using the "daily" config, the utility will think it is writing to the
/var/lib/asterisk/backups/daily directory, but will actually be
writing to /mnt/usb/daily.
I think the best suggestion is to follow what Mike Ashton suggested
with rsync - you actually do the backups to the local hard drive, but
then copy the files over to the USB device. Given the limited number
of write cycles for USB flash memory, this is probably a good idea.
Regards,
Doug.

Subject: [on-asterisk] Backup and restore to a USB stick
Hi all, as many are aware FreePBX has a backup and restore function
that can schedule a backup of conf, cdr, and vmail.
This works very well but I need to back the files up to a USB stick
instead of a default backup directory.
My question (not being a good Linux man) is how do I the redirect the
backup path to this device.
When I plug the stick in, the consule indicates that the stick is
recognised and is working but does't tell me where
in the directory structure to find it.
Help please?
