fbackup block size

HP UNIX Professionals — Tue, 19 Apr 2011 09:13:19 GMT

Hi Experts,

We are running backup in HPUNIX box, I want to know size of the total data backed up in each day.
As per the log the size is reflected in “blocks” NOT in KB or byte.
Anybody know how to calculate the total size please he us.

Eg

Total Size = 634094893 blocks
1 block = ? KB

Last part of the Backup Log File
================================
610895: /w/work/sql24553.tmp 0
610896: /w/work/sql26997.tmp 0
610897: /w/work/sql27945.tmp 0
610898: /w/work/sql6746.tmp 0
610899: /w/work/sql9432.tmp 0
610900: /w/work2 1
fbackup(1005): run time: 10665 seconds
fbackup(1030): warnings encountered during backup
fbackup(3055): total file blocks read for backup: 631597273
fbackup(3056): total blocks written to output file /dev/rmt/0m: 634094893

Thanks in advance

Vinay,

If you do a man on fbackup, it indicates that is assumes a block is 1024 bytes.

I'm glad it's documented. Otherwise it is in useless 512 byte blocks.
