Top Forums UNIX for Advanced & Expert Users Compress files with output to tape Post 6187 by sinardy on Thursday 30th of August 2001 11:08:40 PM
Old 08-31-2001
I forget to tell you that, I am tuning my backup script, our previous script took 8 hours to backup 24 files (total is about 10 GB), the script is something like...

tar cv file1 > log.log
tar uv file2 >> log.log
tar uf file3 >> log.log
tar uf file4 >> log.log
..
..

Note: file1 (1.998 GB), file2 (580 MB)

And one of our partition that need to backup is 45% so that I try not to use our HD as our compressed file buffer before backup to tape.

Thank you,
Sinardy

BDB.DB0(5)							AFS File Reference							BDB.DB0(5)

NAME
bdb.DB0, bdb.DBSYS1 - Contain the Backup Database and associated log DESCRIPTION
The bdb.DB0 file contains the Backup Database, which records configuration information used by the AFS Backup System along with cross- indexed records of the tapes created and volumes dumped using the Backup System commands. The bdb.DBSYS1 file is a log file in which the Backup Server (buserver process) logs each database operation before performing it. When an operation is interrupted, the Backup Server replays the log to complete the operation. Both files are in binary format and reside in the /var/lib/openafs/db directory on each database server machine that runs the Backup Server. When the Backup Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its copy of the bdb.DB0 file matches the copy on the other database server machines. If not, the Backup Servers use AFS's distributed database technology, Ubik, to distribute to all of the machines the copy of the database with the highest version number. Use the commands in the backup suite to administer the Backup Database. It is advisable to create a backup copy of the bdb.DB0 file on tape on a regular basis, using the UNIX tar command or another local disk backup utility. SEE ALSO
