[gpfsug-discuss] mmbackup and filenames

[Buterbaugh, Kevin L]

All,

I would like to see this issue get resolved as it has caused us problems as well.  We recently had an issue that necessitated us restoring 9.6 million files (out of 260 million) in a filesystem.  We were able to restore a little over 8 million of those files relatively easily, but more than a million have been problematic due to various special characters in the filenames.

I think there needs to be a recognition that TSM is going to be asked to back up filesystems that are used by Windows and Mac clients via NFS, SAMBA/CTDB, CES, etc., and that the users of those clients cannot be expected to not choose filenames that Unix-savvy users would never in a million years choose.

And since I had to write some scripts to generate md5sums of files we restored and therefore had to deal with things in filenames that had me asking “what in the world were they thinking?!?", I fully recognize that this is not an easy nut to crack.

My 2 cents worth…

Kevin

The problem is that the Tivoli Storage Manager (Ahem Spectrum Protect) Filelist option has some limitations:

...
The files (entries) listed in the filelist must adhere to the following rules:

  *   Each entry must be a fully-qualified or a relative path to a file or directory. Note that if you include a directory in a filelist entry, the directory is backed up, but the contents of the directory are not.
  *   Each path must be specified on a single line. A line can contain only one path.
  *   Paths must not contain control characters, such as 0x18 (CTRL-X), 0x19 (CTRL-Y) and 0x0A (newline).
  *   By default, paths must not contain wildcard characters. Do not include asterisk (*) or question marks (?) in a path. This restriction can be overridden if you enable the option named ... AND SO ON...


IF TSM would implement some way of encoding or "escaping" special characters in filelists, we would happily fix mmbackup !
