vdump size reporting
We are using a Tru64 machine with a robot to perform backups, some of the areas being backed up are mounted via NFS. When performing the backups i have noticed strange things in the reporting from vdump
Below is the output from the vdump and a df from the area being backed up.
Does anyone have any ideas why these numebrs dont match ???

Re: vdump size reporting
since the drive is not blocked while backup, it is possible, that usage and number of files since the begin of the vdump change.
Dumping 1567027550 bytes
Dumped 2867494715 of 1567027550 bytes; 183.0% completed
this means, that one file has increased a lot during the backup.
greetings,
Michael

Re: vdump size reporting
Backup open file is not a good idea, left the file in an unknown state.

Re: vdump size reporting
I simply think that you are backing up an active file system. Looks like your filesystem has some files which are open and this probably is the reason why your nos don't match.

Re: vdump size reporting
It's quite unlikely that anyone was doing anything at that time, and even so the disk utilisation growing by such a large amount ????
Anyone have any more ideas ??

Re: vdump size reporting
vdump does a statistic of what it has to backup before it starts the backup. When after that files get bigger then you have backuped more than 100%. You can count on it, that during the backup the file set got bigger. Maybe not by this machine, but by another machine, which also has this nfs drive mounted.
