We came across this problem recently when trying to update one of our customers from Shadow Protect (SP) from v 3.5 to v 5.0.2. The problem is that you have to uninstall v 3.5 with the v5 installer which then removes the backup job. When you install V5, you have to create a new backup job or try to restore the previous backup job via a registry edit http://www.storagecraft.com/support/kb/article/191 which works fine from v4 but not v3 (last comment in this link)http://www.storagecraft.com/support/forum/upgrade-shadowprotect-v352-v5 So when you create a backup in v5 it will start from scratch and will not continue the chain which forces a new SPF (full file) backup. When running on a local LAN this isn’t such a problem, but when your customers are uploading a full bare metal image via the internet to our servers, this is a huge problem.
This solution worked for me:-
Upgrade v3.5 to v4.15 – restart server
Upgrade v.4.15 to 5.0.2 – restart server
After restart, open SP and allow to run as normal. It will continue where the chain left off which means continued small file backups!
V4.15 has an earlier installer and doesn’t request you to uninstall v3.5
I have run this upgrade on 4 servers (2 x 2008 64bit 1 x 2008r2 and sbs2008) and all have worked fine. I would stress you test this in a test environment first before running on a live system.
I hope this helps others out there
