Backup

of

Xrootd

FGST
...
data
...
to
...
HPSS
...
The
...
FGST
...
xrootd
...
cluster
...
is
...
integrated with
...
HPSS.
...
New
...
files
...
that
...
are
...
copied
...
into
...
the
...
xrootd
...
cluster
...
are
...
marked
...
that
...
they
...
have
...
not
...
been
...
migrated
...
to
...
HPSS.
...
Not
...
all
...
files
...
that
...
are
...
copied
...
to
...
xrootd
...
are
...
backed
...
up
...
but
...
currently

only

some

of

the

produced

files.

The
...
list
...
of
...
files
...
that
...
should
...
be
...
migrated
...
to
...
HPSS
...
is
...
produced
...
daily
...
and
...
is
...
used
...
by
...
the
...
migration
...
tools
...
to
...
transfer
...
files
...
to
...
HPSS.
...
Once
...
a
...
file
...
has
...
been
...
migrated
...
to
...
HPSS
...
it
...
is
...
marked
...
as
...
migrated
...
so
...
that
...
it
...
will
...
not
...
be
...
migrated
...
again.
...
There
...
are
...
three
...
lists
...
of
...
L1
...
files
...
to
...
backup,
...
found
...
in
...
~glast/_backupfiles. Each line of these files contains:
size, checksum, filename
