File system file corruption

[fmaggio01]

Hello all,


On my AIX server there are some paths that include ? in them.


/backup/dbms/VP/P?/O
/backup/dbms/VP/P?/O-REC

I can back them up, but when I try to restore I get an error, are ? normal for AIX operating system paths. I've talked with two AIX people one says ? are normal to see, other one say they are not and a ? in the filepath is sign of file system corruption.


Can anyone confirm?

can it be your backup software/solution issue?

at least when I try to restore test-starnge-named files with GNU tar and rsyc, I get no errors, so you should also get no errors with "?" I think....

Thanks w5000!

I'll contact the backup vendor about the restore errors.
