The problem with small files is that the TSM database entry may well be larger
than the file you are storing. If your files are less than about 3000 bytes
that will be the case.
What is happening is that the file system is being used as a database. A
complex file path becomes the key

I suggest you provide a few more details about the data and you backup
environment.
For example; what is this data, how frequently will it be accessed on average,
what is its total space requirements, what is the source stored on?
Type of backup storage; tape, disk, cloud? (specifics)
Bo,
this is easy if you just use the right filesystem to hold the data :-)
We have multiple very large scale customers using IBM Spectrum Scale for
this.
Environment: Medium IBM Spectrum Scale installations with a single digit
number of nodes and file systems. IBM Spectrum Protect backup archive
Hi TSM's
I have earlier asked for help with archiving of 80 Billion very small files,
But now they want the files backed up. They expect an average change rate of 3
percent/Month.
Anyone with experience of such an exercise, and will share it with me??
Regards
Bo
