    I have a few questions regarding WHM's Backup option. I've never really used it, so I want to make sure I'm not messing anything up.

    I have a server dedicated to one site. The site is HUGE, and has roughly 600,000 page views a day (expected to be closer to 12,000,000 within the year). It has a MySQL database tied to it that's about 4GB, and has about 500,000 text files in 60,000 directories that are used for visitors to send Private Messages, etc.

    Example:

    /home/mydomain/userpath_1/[user]/inbox.dat
    /home/mydomain/userpath_1/[user]/sent.dat

    /home/mydomain/userpath_2/[user]/inbox.dat
    /home/mydomain/userpath_2/[user]/sent.dat

    And so on. There are currently three /userpath_[X]/ directories, and the first two have 30,000 [user] directories in them (the third isn't full, but when it has 30,000 users, the system will create /userpath_4/).

    Knowing that, here are my questions:

    1. How reliable is WHM's backup? Would I ever run the risk of being in the middle of a backup, hitting an error (ie, high server load crashes the server), and losing everything?

    2. In the configuration, I want to have a daily backup, but even in the worst case scenario, I would never want to restore anything more than a day old. Under "Backup Retention", so I uncheck Weekly and Monthly? I'm guessing that's what's meant with this section, but there's no explanation so I wasn't sure.

    3. Is there a reason to NOT enable "Incremental Backup"? Generally, it sounds better to only backup what has changed that day, but not if it's significantly slower. Are there issues with this that I should know?

    4. Am I correct in assuming that "Backup Accounts" would back up everything from my site? Including the Private Message folders mentioned above?

    5. Assuming so, is there a reason to NOT enable "Compress Account Backups"?

    6. Under "Backup SQL Databases", is there a reason to not select "Per Account and Entire MySQL Directory"? Remember, there's only one account on this server.

    7. I have a second hard drive on my server named /backup/, and this is the destination for the backups (naturally). Should I list it as "/backup", or "/backup/" (note the trailing slash)?


    If there's any other advice you can offer, please feel free to let me know. I might be paranoid, but the site has 8 years worth of data; if I lost any of it by running an untrustworthy program, it would have major ramifications for me.

    TIA,

    Jason
