Automatic Backup Using ontape

Posted in 2005

Summary

A user on IDS 9.21/UnixWare 7.1.1 asked how to run unattended nightly ontape backups from cron. Several people supplied working recipes: the key trick is feeding ontape the carriage-return it waits for, e.g. piping an echo of a newline into "ontape -s -L 0" (or using a here-document with a blank line), redirecting output to a log file, and setting INFORMIXDIR, INFORMIXSERVER and ONCONFIG in the script. Suggestions also included pre-creating the backup file in the TAPEDEV path with 660 perms, gzip-ing the archive afterwards, checking tape readiness with tapecntl, and grepping the log for "100 percent done." or errors to verify success. Problem effectively resolved by these sample scripts.

Something like this: # begin of script ontape -s -L 0 <<EOF 1>>your_log_file 2>&1 EOF # Yes, leave a blank line after ontape! # end of script In case you backup to disk you can compress the archive file on the fly.

Avichal, ## Fire off the script via Crontab. ## Set INFORMIXDIR, INFORMIXSERVER and PATH ## The second " is on a new line.

1.- Create Shell Script, with SERVERNAME, INFORMIXDIR, ONCONFIG variables. INFORMIXSERVER=(Instance) ONCONFIG=(onconfig file) INFORMIXDIR=(pathname) 2.- Create backup filename in the same path than TAPEDEV variable of onconfig file. > /(Path)/backup 3.- change perms to rw-rw---- (660) chmod 660 /(Path)/backup 4.- Execute ontape level 0 command. ( Non interactive way ) echo "\\ 0" | $INFORMIXDIR/bin/ontape -s -L 0 5.- If you need keep space you can compress the file with gzip command gzip /(Path)/backup --- "Avichal A N...." <avichal@cjpatel.com.fj> escribió: > Hi > > Can somebody help me setup an automatic backup using ontape.
