Intriguing, I might need to try this sometime. Nice to know of this

The specifics would be OS-dependent, but the general gist would be
something like the following:
1) make a DOS-friendly-named "mail.img" file to act as a virtual disk.
I'm specifying 100MB here, but choose a value appropriate for you
$ MAILIMG=/mnt/fatusb/mail.img
$ MOUNTPOINT=/mnt/mailbackup/
$ mkdir -p ${MOUNTPOINT}
$ truncate -s 100MB ${MAILIMG}
2) make a filesystem on it and get the system to recognize it as a
device. On Linux, that might looks something like:
$ /sbin/mkfs.ext4 ${MAILIMG}
# DEVICE=/dev/loop0
# losetup ${DEVICE} disk.img
On FreeBSD for UFS, you'd create a memory disk and format it:
$ su -
# MD_IDX=0
# mdconfig -f ${MAILIMG} -u ${MD_IDX} # create md${MD_IDX}
# gpart create -s gpt md${MD_IDX} # set up GPT partitioning
# gpart add -t freebsd-ufs md${MD_IDX} # create a partition in that
# DEVICE=/dev/md${MD_IDX}p1
# newfs ${DEVICE} # format it with UFS
3) mount the loopback/memory-disk device someplace:
# mount ${DEVICE} ${MOUNTPOINT}
4) use the device mount-point for your backup, such as
$ rsync -avr ~/Mail/ ${MOUNTPOINT}
5) unmount it:
# umount ${DEVICE}
6) destroy the loopback device:
On Linux:
# losetup -d ${DEVICE}
On FreeBSD:
# mdconfig -d -u ${MD_IDX}
Once you have the disk-image file, you can skip the
partitioning/formatting commands (gpart/mkfs.ext4/newfs) and just
create the device (losetup/mdconfig), mount, use, unmount, and
destroy the device. Linux's mount(1) even knows about loop-back
devices so you can just create/mount in one step, and
unmount/destroy in one step:
# mount -o loop ${MAILIMG} ${MOUNTPOINT}
use the disk
# umount ${MOUNTPOINT}
There may be a simpler way of doing it on FreeBSD, but I just use the
mdconfig/mount/use/umount/mdconfig-d sequence and it Works For Me(tm)
You might also be able to use some nice ZFS functionality if it was
available, but that is a little more convoluted (importing/exporting
pools in particular).
Sorry if that's more complicated/convoluted than you want, but it
does give you "full Unix-like filesystem functionality on a
DOS-formatted USB drive".

The only problem I have with this is that the way I run rsync, I
create backup copies of any modified file before overwriting and store
those in an archive folder until they are sufficiently old, then
delete. So if I create a .tar or .zip file it will basically move the
old copy and replace with the new copy on every backup, which,
given the size of the archive, takes too long to suit me, besides
eating up available storage too fast.
What I'm actually doing now is similar to what you suggested above,
but I'm creating and updating the zip file directly on the USB flash
drive using zip -FS. So I'm not using rsync for mails, only for
everything else. This seems to be working fine so far, only drawback
being there are no older copies being archived as everything in the
zip file gets synchronized to the filesystem, but that's okay for this
situation.

A little late to this game, but a couple other ideas occur to me:
- back up to a .tar file (or maybe a .zip file?) instead of directly
to the file-system. That way, a DOS-acceptable .tar (or .tgz)
filename exists in the FAT partition, while its contents contain
filenames containing colons. This (to the best of my knowledge)
doesn't take advantage of any rsync linking/deduplication your
script may be doing
- create a file such as "mail.img" on your FAT partition, format it as
something smarter (e.g. ext{2,3,4}, UFS or ZFS), and mount it as a
loop-back/memory-disk, to which you can then use rsync to that
loopback device. This allows for actual sym-links and hard-links
which rsync can use for deduplication (using the --link-dest
option[1])
- reformat the USB drive as something smarter than FAT (whether
ext{2,3,4}, UFS, ZFS, or maybe NTFS?). This does come with the
disadvantage of being harder to read on Windows (though I've seen
some Windows drivers that allow you to mount EXT2 partitions under
Windows) but would ameliorate all your other issues. Given the
(un)reliability of USB drives, there's a lot to be said for
creating a ZFS pool out of the drive and setting copies=2 to give a
better chance at recovery

If you really need FAT32, I'd suggest creating a container on the flash drive using dd, and then format that container with a file system capable of colons. Then just mount the container (mount -o loop) and rsync into it. Rainer signature.asc Description: Message signed with OpenPGP

Certain programs have the ability to mangle filenames for filesystems that don't support certain characters. rdiff-backup for instance will also mangle filenames with upper/lower casing for case-insensitive filesystems to prevent collisions.

Thanks for your reply. I use a one line rsync command from a shell script to recursively backup my file tree so I'm not sure how any of the above suggestions could be incorporated into that. I've thought about using a script to replace ":" with another character but I could not do that very well _in place_ as I assume that could mess up mutt, or at least cause mutt to rename the file back. OTOH, to copy all the files to another location to rename, and then backup from there, seems like a bit of overkill. > -- > (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri > http://en.opensuse.orgopenSUSE Community Memberfacebook/ptilopteri > Registered Linux User #207535@ http://linuxcounter.net > Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode

How to backup emails with colon in file name
I use rsync for doing incremental backups to a USB stick. I am having a problem that rsync does not like backing up my mutt emails since they contain a colon in the filename. For example: 1498570870.M370636P2743Q2R5bbb999d0aefc481.net1:2,S Using fat32 format on the USB stick may be part of the problem but I don't want to change to a different format for other reasons. What is the best way to backup these emails or how do others handle this? Thanks for any help. -- Jason
