What do you like best?
I am a database guy and daily deal with Db backups and came across multiple tools which directly backsup data to tape, since I started dealing with Netbackup, I found it useful, easy to use, configurable and most important reliable. Reliability is the most important factor when dealing with backups and restores and in last 4 years of it;s usage I never faced any issue while recovering a backup. it do what it is designed for. Other useful factors are it has de-duplication features, policy controls, various scheduling options, long term backup retention possibility, etc. it's definitely a industry standard for backups and compete strongly with other solutions out in market.
What do you dislike?
I dislike that,
-It doesn't provide end to end encryption for Db backups, not sure about file system.
-It has retry feature but it still fails with Exit code 1 and there is no way to get it overridden, I dislike this because in my system, failures are linked with tickets so even after retry if it succeeds, ticket will still come to me and I hate that seriously
Recommendations to others considering the product
if you are an administrator (database, windows, storage, application, etc.) and your requirement is to backup everything to tape and would like to override the disk at middle layer then consider Netbackup in POC/estimation analysis because this is very useful and reliable utility which can backup and restore and with incorporating virtual tape library, recovery can be faster as disk recovery. This tool has graphical interface which is very useful and works well with command line, the help available is sufficient enough to cover most common and day to day issues and available on Symantec own portal/forums. I have done backups and recovery ton times and 99.99% went through without any issue. There are few caveats and fallback too but it all depends upon environment to environment and that is where testing and proof of concept is required.
