Raw Device Backup
We have to perform an activity for one of file system to increase the inode value which requires format of filesystem with new inode value.Prior to activity we have to backup the mount point. Now the problem is that this mount point is having millons of files and standard backup is taking very long time. We can't use the Flash backup as it is Linux machine using LVM and Flash backup is not supported in this scenario.
I tried taking backup using RAW device and backup is perfectly doing fine with very good speed. But I am not sure, when I will do the restore, will the inode or other file system attribute will change or not.
Another option to create a new file system and copy content of source to target file system with dd command. Here I am also not sure, will it chage the file system property doing restore back.
Any other option if above didn't work ?
