在AIX中如何使用vg备份恢复的方法将数据转移到新存储设备(国外英文资料) In AIX, how do you use the VG backup / restore method to transfer data to a new storage device? Contributors: Yan Xu With the update of the device, users will often encounter data transfer problems. How do you transfer data from an old storage device to a new storage device? Well illustrate how to use AIXs VG backup / recovery method below. The savevg command can backup all the contents of vg. The restvg command restores VG; LV; file. The restorevgfiles command restores files to its original directory. VG backup / restore method: Our approach is to backup the vg-local (built on the local disk hdisk1) to the tape rmt0 and revert to the hard disk hdisk4 provided by FAstT600. Stop application Backup data must be stopped. Stop with ctrl-c We stopped work with ctrl-c in another telnet: ...... A /mnt/lv-local/usrlib/libauthm.a 22 blocks. A /mnt/lv-local/usrlib/libc128.a 132 blocks. A /mnt/lv-local/usrlib/libc_r.a 13847 blocks. A /mnt/lv-local/usrlib/libc_t.a 3007 blocks. ^Cp615:/ Synchronous data P615:/sync Note: Never use the umount filesystem. Since the savevg command is file based backup, it only searches for valid files in existing file systems (not backed by blocks of data). Files that exist in umount in LV will not be backed up. Here is another failed recovery, /dev/lv-fastt600-1, because the backup did not backup the case on the /dev/lv-fastt600-1 mount. So there is no backup 0./mnt/lv-fastt600-1 0./mnt/lv-fastt600-1/lost+found 9379840./mnt/lv-fastt600-1/usrlib.tar Officially, the backup saves the tape and restores SHRINK the filesystems.
