I dumped the filesystem as follows: ---------------------------------------------------------------- root@antsrv1 [~] # dump 0cafb /dev/nrsa0 1000 /export/solaris DUMP: Date of this level 0 dump: Thu Sep 27 11:14:06 2001 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/twed0s1d (/export/solaris) to /dev/nrsa0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 3416548 tape blocks. DUMP: dumping (Pass III) [directories] DUMP: 0.03% done, finished in 0:56 DUMP: dumping (Pass IV) [regular files] DUMP: 38.99% done, finished in 0:07 DUMP: 75.28% done, finished in 0:03 DUMP: DUMP: 3407516 tape blocks on 1 volume DUMP: finished in 783 seconds, throughput 4351 KBytes/sec DUMP: Closing /dev/nrsa0 DUMP: DUMP IS DONE ----------------------------------------------------------------- Trying to retrieve the data yields: ---------------------------------------------------------------- root@antsrv1 [/export/stuff/restore] # restore xfb /dev/nrsa0 1000 bad name to addentry ./openwin/lib/X11/locale/C/help abort? [yn] y dump core? [yn] n ------------------------------------------------------------------- Browsing through the tape with 'restore -i' shows that the directory ./openwin/lib/X11/locale is empty! I than did the same dump to a local file to rule out any tape problems -- same result. Am i making any mistake? Is the filesystem too large (about 10 G)? Or should i go for a different backup software? Any help would be greatly appreciated. -- Heinrich Rebehn University of Bremen Physics / Electrical and Electronics Engineering - Department of Telecommunications - E-mail: mailto:rebehn@comm.uni-bremen.de Phone : +49/421/218-4664 Fax : -3341 --------------------------------------------- Leon : And stop saying "okay" all the time!
