Please re-read the fAQ and the TOP-TEN-QUESTIONS in the docs dir, and then give your machine a unique name. localhost is not unique. >> (16:46:53) Use of uninitialized value in printf at >> /usr/sbin/amstatus line 760.

When it is done, what speed is reported in the email the dump sends you? By that, I mean does it match within say 10% of the drives rated speed of data transfer? Also, note the holding disk area of only 296,960k, (297 megs) which is not nearly enough for amdump to stuff a 17,720,729k (18Gb? break that into subdirs and use tar, not dump if thats what you are now using) dump, and this is forceing amdump to write directly to the tape, possibly with lots of under-runs that will result in the drive stopping, backing up and restarting (shoe shining) which takes time out of the write time, so I'd expect the write speeds reported to be a bit slow. So in addition to giving the machine a unique name that can at least be resolved in the /etc/hosts file, find it some more holding disk area. The localhost issue probably won't effect the backups, but it sure will mung any chances of a clean recovery should you need it. > >Max. > >Max Waterman wrote: >> Thanks everyone for helping. >> >> I got email working (albeit only locally since my isp is blocking >> my [chinese] IP address), so now I can get the reports. >> >> I bought some more tapes, and have used the amrmtape command to >> start from scratch.
