7.2. Initiating Backup Operation

The BackupRun method is used to initiate the backup operation. The comparison method used is set using the "bydate", "bysize", "bynewerdate", "bynewersize", "bycrc", "bymd5", or "bysha1" keywords. If "bynewerdate" or "bynewersize" is selected, the the source file will be copied to the destination only if it is newer or larger.

The BackupRunV method is used to initiate the backup operation and verify each transferred file after transfer using crc, md5, or sha1. The "bycrc", "bymd5", or "bysha1" keywords are used to set the verification method.
