Catalog backup size not reduced after catalog compression
- 11 years ago
This is something you may need to test more as it depends on how things work with the catalog compression.
I have dug through my old notes for a customer i dealt with a few years ago who used compressed files on their systems (windows compression)
During the tests we backed up a folder containing their compressed files - it backed up 5 GB of data in 33 minutes
We then uncompressed the files and ran the backup again - this time it backed up exactly the same amount of data but it only took 11 minutes - so three times as fast.
This suggested that that type of compression caused the files backed up to be uncompressed in the backup stream causing a overhead on the backup and really slowing it down - and still reporting the full backup size
As those folders showed up a blue in Windows explorer the same as the catalog files do that you have then i assume it uses the same type of compression method and from that i assume it will do the same during the backup
I do not see that documented anywhere but i do have my test results to work from
Hope this helps
