replicating / syncing directories

[Roberto Martinez_6]

Hi,
is there a faster way to sync directories or filesystems (copy/move all the data from one to another) than the famous
tar cf - * | (cd dest; tar xf)?
TIA

[Robert-Jan Goossens]

Hi,

# find /opt | cpio -pcmudv /otherrFS

Hope it helps,

Robert-Jan.

#cd /home
#find . | cpio -pudlm /duphome


Thanks

You could also user fbackup/frecover, example from man frecover to copy /usr to /mnt:

fbackup -i /usr -f - | (cd /mnt; frecover -Xrf -)

or even vxdump/vxrestore (assuming VXFS filesystems), similar example from man vxrestore:

vxdump 0f - /usr | (cd /mnt; vxrestore xf -)

John

Thanks to all:

1. didn't find rsync on hpux.
2. tar: 5min20sec. cpio: 4min42sec. Great!

Roberto:

If you really want to have sync'ed filesystems, then
install and use HP MirrorDisk/UX.

You will have one filesystem to access, but data are
mirrored, automatically. It is very fast, synchronization
is done in the background and on-line.

HP MirrorDisk/UX is not good for backups, but for hardware
failures (disks, SCSI controllers, cables, and so on).

thanks, in fact what I wanted is to MOVE data across different disks.

From some testing that I've done, the vxdump/vxrestore method seems about the same speed as find/cpio. It also has the advantage that it supports largefiles where cpio doesn't.

John
