I am not proficient in the use of Symantec Backup Exec, I will like to know what is the best known backup strategies for a simple file server. I have 5 LTO 3 cartriges new and available to start this strategy but don't know what will be the best approach.
I though to do one weekly on Friday (full in disk 1) and then an incremental everyday until next friday (in disk 0) then another full in disk 2 and so on. Is this the best way.
Thanks.

Setting up a new backup scheme
Without knowing what the answers to my questions in the comment, I'd go with:
Tape rotation will depend on how much data. I'd have separate tapes (or sets of tapes) that I use for full backups and for the differentials. If your full backup fits on one tape and all the differentials also fit on one then you'd get something like:
You say you have 5 cartridges, but LTO3's are cheap enough now that you can buy some more. I'd keep at least the last 4 fulls, and I'd have at least 3 or 4 diff tapes to rotate through. When we were only using tape, we'd keep the last full of each month for one year, and we'd keep two of the fulls forever. You'll need more tapes w/in a month if you want to do something like this.
If it takes more than one tape for a full, you'd adjust as necessary, and obviously you'd need more tapes up-front.
"Best" is a relative term. It really depends on what you're backing up and how important it is to get that data quickly.
Most important items first: make sure you take backups offsite! I know that's not mentioned in your question specifically, but the reminder never hurts. You can pay Iron Mountain to do it for you, take the tape to a safe-deposit box, or take it home. And encrypt that tape while you're at it.
A pretty easy-looking way to set up BE is to use the Policy wizard. In Backup Exec 11d (assume it's still there for newer versions) that will help setup a Grandfather-Father-Son media rotation for you to the backup device of your choice. In 11d, select Backup-->New Policy Using Wizard. I just skimmed it on my backup server, but it should walk you through the details of setting it up. This will let you go back up to a year. Also, if you use the Vaults, you can tell exactly where your tape is (off-site, online, under the mattress, etc.)...if you tell BE where your tape is when you Inventory.
The drawback is that by default it will require more tapes. In fact, you'll need 6 tapes just to make it through the week, as each daily incremental will be on a tape and overwrite protected. This can be nice, but 5 LTOs won't cut it! Best case, you'd have 12 tapes for a year's worth of monthlies, 5 tapes for a month's worth of weeklies, and 5 more for a week's worth of dailies.
Remember that if this is doing any sort of database stuff (mail, SQL, etc.), you probably need some sort of agent for BE to really back it up.
Hope this helps! CC
There is no best strategy. Backup type, frequency and content are all determined by whatever the buisness requirements are.
