Copyinmg files from one filesystem to another

[Madhu_17]

Hi Friends,

I would like to copy files from one filesystem to another. i'm using the below command

#find . -depth -print | cpio -pdlmuv newdir

but i'm facing problem with the link files. file timestamp is updating with the current date. even the source and dest. directories sizes are mismatching. I'm not facing any problem with other directories time stamps and owner permissions.

Can anybody suggest me a better way to do this activity?


Thanks,
Madhu

Basically the only other way is to utilize your favorite backup/restore software. Take a fresh backup then restore it to the new location. Most (good) backup/restore packages allow you to restore to a new location yet keep the old dates.

We don't have that much outage window. We need to finish this in 1-2 hrs. so, we are planning to do this directly fm. one filesystem to another.

any suggestions please?

madhu,

cpio only preserves time stamps of all except link files and directories - the man pages should be clear on that.

If you want everyting to be "preserved" use vxdump/vxrestore:

vxdump 0f - /sourcefs| (cd /targetfs;vxrestore rf -)

Madhu,

Forget not to clean your target Filesystem -- either rm -r /tgtfilesys/* [except lost+found) or unmount the tgtfilesystem and mkfs ..
