RE: [BackupPC-users] Moving filesystems OR upgrading RAID

[Leon L. <le...@le...>]

Hi Chris,

That almost worked.  Here is the exact command I am running.
tar cp /backupdata | tar xp -C/temp_backup

Now it starts copying right away but I am getting "invalid cross-device
link" errors.

Thanks for all you help.

Leon

DOH!  Les just made me realize i forgot an important detail.

the tar command should have read:

tar cp /backup/BackupPC | tar xp -C/mnt/newdisk

sorry 'bout that.
