copy filesystem

[Satish Y]

Hi,

We have two HP-UX 11.11 systems, which we are using one as standby for the other, say server A & B.
As a part of one activity, we had to copy one filesystem of 5.6 GB from server "A" to "B". We have exported filesystem on server "A" and mounted on server "B" using NFS.
Then, copied files on "B" using "cp -pR" from NFS mounted filesystem to local filesystem, but it took more than 7 hrs because of large number of files(675,000).

Is here any other method with which we can transfer the files faster?

Cheers...
Satish.

Hi Satish,

You could try to use a fbackup/frestore.

something like below command.

# fbackup -i /source -f - | remsh server "cd /copy ; frecover -Xrf -"

or cpio.

# cd /source
# find . | cpio -o | remsh server " cd copy ; cpio -idum "

Hope this helps,
Robert-Jan

Hi,

Do you use DataProtector or another backup tool ? A very fast method for copying large filesystems with lots of small files is to do a disk image backup/restore.

Fbackup or what I found to be faster - vxdump/vxrestore:

timex vxdump -0 -f - -s 1000000 -b 16 /oracle | (cd /mnt/oracle ; vxrestore rf -)
