5. Zip up small files and exclude the originals from backup
If you have millions of small files which rarely change, you can improve TSM performance by only backing them up in zipped-up form. If a large number of files is zipped into a single file, then TSM only has one object to deal with, rather than the large number of files which it previously needed to count.
Once you have compressed your data, you may wish to delete the original files, and only keep them in their new format. However, if you still need to keep the uncompressed form of your data on disk, you can exclude the original files from backup, using our instructions on how to exclude files, folders and drives from backup.
