log file for fbackup

hi, Please allow me to ask you guy a stupid question :
1. as per log below, 1 block is equivalent to how many mb ?
2. the total block write to output is different from total read, does it mean that my backup got problem ?

/home/oraprod/dbackup.sh: /home/applprod/fbkp.log: Cannot create the specified file.
fbackup(1004): session begins on Fri Jun 8 02:30:00 2007
fbackup(3024): writing volume 1 to the output file /backup/prod
fbackup(3055): total file blocks read for backup: 162486343
fbackup(3056): total blocks written to output file /backup/prod: 162637358

Re: log file for fbackup

It does not look like errored. Try to check the exit code of fbakcup command in the script.

Re: log file for fbackup

1)1 block is generally 512 byte .
2) Seems no problem in the backup .check the exit status of fbackup.

Re: log file for fbackup

Hello

1) From fbackup(1M):

Note also that the blocksize used in
earlier releases (7.0 and before) was 512 bytes, whereas it is now
1024 bytes. This means that the same value specified in
blocksperrecord in an earlier release creates blocks twice their
earlier size in the current release; for example, a blocksperrecord
parameter of 32 would create 16-Kbyte blocks at Release 7.0, but now creates 32-Kbyte blocks.

2) It is normal behavior of fbackup for blocks_read <> blocks_written. As no errors were logged during the backup process, you should be fine.

Re: log file for fbackup

thanks everyone for all your kind response. My backup file is about 80GB, if 1 block = 1024bytes (1kb) , it means that total written to outpout file is almost double up my backup file, am i right ? does it has any problem ?

thanks

Re: log file for fbackup

hi,

please port the exact command you have used (fbackup)

and also the file systems that you are backing up.

du -sk /

There is insufficient information here that we can use to analyse.

kind regards

Re: log file for fbackup

hi,

We need to investigate further into the online index file generated. This file consists of one line for each file backed up during the session. Each line contains the file size, the volume number on which that file resides, and the file name.

In your case, the file is:
/tmp/index

please check its content if it is according to what is expected...

kind regards
yogeeraj
