The daemon backup tool
The backup tool, which we will call backupd, will be responsible for periodically checking the paths listed in the filedb database, hashing the folders to see whether anything has changed, and using the backup package to actually perform the archiving of the folders that need it.
Create a new folder called backupd alongside the backup/cmds/backup folder, and let's jump right into handling the fatal errors and flags:
func main() {
var fatalErr error
defer func() {
if fatalErr != nil {
log.Fatalln(fatalErr)
}
}()
var (
interval = flag.Duration("interval", 10 * time.Second, "interval between
checks")
archive = flag.String("archive", "archive", "path to archive location")
dbpath = flag.String("db", "./db", "path to filedb database")
)
flag.Parse()
}
You must be quite used to seeing this kind of code by now. We defer the handling of fatal...
