Since fbackup(1M) from 11.31 cannot be restored to fbackup to 11.23, I am forced to dd since files are more than 8 Gb
Please let me know the command syntax via dd to take the backup of mutiple folders to tape drive and the procedure to restore the same
I am little confused with dd(1)
Points will be assigned appropriately !!
Solved! Go to Solution.

SolutionSince you can't use 'frecover' to restore an 11.31 'fbackup' archive to 11.23 or earlier, I would use 'pax' to perform your backup. By using the '-x pax' archive format you can exceed the former 8GB limit when you create the archive.
Then, on 11.23, install the 'PAX-Enh' product to enable reading the large files:

_GNU_ "tar" should be able to do it. "dd"
seems (to me) to be an inappropriate tool for
a job like this.
> [...] I would use 'pax' [...]
Should also be good, if your "pax" programs
are new enough.

Analyst: Its good, but the command is good for device backup
Do we have command to take backup for directory
James:
This is what I was expecting.
Steven: Thanks for your advice on dd
GNU tar: Its open-source !!

Re: How to take and restore from dd
fbackup -v -f /dev/rmt/1m -i /u01
To take the fbackup via pax
# pax -w -f /dev/rtape/tape4QIC150 /u01 -x pax
How do I restore it.

Pretty much the same as tar except the options are rationalized:
# pax -r -f /dev/rtape/tape4QIC150 -p e

Re: How to take and restore from dd
It took 3.5 Hrs for 260GB database using pax and same is taking only 2.5 Hrs for the same size using fbackup.
Do we have any docs which refer to the speed at which the backup tools takes time
Are there any options in pax command which gives total time at end, like fbackup does ??
