I have compiiled and installed the latest Amanda 2.4.2p1 for an
installation of DEC Unix 4.0b to 4.0d, HP-UX, Solaris, Irix, and NT
(Samba) workstations. Amanda successfully backs up 70+ file systems from
these platforms to the default 'DailySet1', with a dumpcycle of 4 weeks,
runspercycle of 20, and tapecycle of 25 tapes. All backups use native
dump, e.g. dump, xfsdump, vdump.
I have created an archival set 'Monthly' for off-site storage. This
shares the same 'disklist' as DailySet1. The only difference from the
DailySet Amanda config is that I have set 'dumpcycle' to '0' and 'record'
is 'no'. Level 0 dumps result for all file systems, as expected from the
'0' dumpcycle setting. However, I find that the 'record no' option is
causing failures for the DEC Unix 'ufs' dumps. Every other file system,
including DEC 'advfs' is processed okay.
Below is listed the 'sendbackup' debug output, along with a listing of
standard output from the DEC Unix 'dump' command, piped as for Amanda, and
with and without the 'u' option to update /etc/dumpdates.
The intermediate 'amstatus' output shows that the dump seems to proceed to
dump completion, where "dump: Actual: xxxxx blocks output to pipe" is
expected.
The only difference between the 'no-record' and 'record' (u) dump option
is the addition of the 'dump: Level 0 dump ...' line. In checking
'sendbackup.c', I see that the error output results from a dump-size of
'-1', which is the initial value. I don't understand why I don't see how
this minor difference would affect the dump_size calculation.
Any help appreciated.
(Note that if I set 'record' to 'yes', the 'Monthly' set DEC Unix 'ufs'
dumps are processed without a hitch.)
