Everyone who has used USB memory sticks know that they are not as fast as HDDs. One thing that instantly comes to my mind about your saying that you want a "reliable" backup scheme with flash devices, is that every flash-based device has a certain lifetime with the number of writes. I don't know exactly how many writes beyond which the device will start failing, but it is still an issue for automated backups especially if they are done frequently, unless you have done enough tests on it to find it out.
I will not consider a backup scheme "reliable" if it encompasses flash-based devices exclusive (i.e. without other media for backup). So I am rather sceptical of the latest gadgets a.k.a. solid state disks which also use this kind of flash technology, especially because they are so pricey (but also with inherent write limitations).

UKOPP(1) Ukopp man page UKOPP(1)
NAME
Ukopp - copy files to USB stick or other disk or disk-like device
SYNOPSIS
ukopp [ -nogui ] [ -job | -run ] jobfile
DESCRIPTION
Ukopp is a graphical menu-driven program operating in its own
window. Ukopp copies the files and directories specified in the
job file to disk or disk-like media (e.g. USB stick).
OVERVIEW
Ukopp works incrementally: only files that are not already identical
on the target media are copied (new and modified files or files newly
added to the backup job). Files/directories to include or exclude can
be selected from the file system hierarchy, using a GUI navigator.
Specifications are saved in a job file which can be re-edited and/or
executed. Ukopp can be run in batch mode using the -nogui option.
Ukopp can optionally keep old file versions instead of replacing them
with updated versions. The retention time and/or the number of old
versions to keep can be specified for each selected file or directory.
File owners and permissions are retained even if the copy media has a
Microsoft file system.
Summary of functionality:
- Copy files incrementally with optional file version retention.
- Three media verification modes: full, incremental, compare.
- Report disk:backup differences in detail or summary form.
- Select and restore files from backup media or use drag and drop.
OPTIONS
Command line options:
[ -job ] jobfile open job file for editing
[ -nogui ] -run jobfile execute a job file
SEE ALSO
The online user manual is available using the menu Help > contents.
This manual explains Ukopp operation in great detail.
