Colonial Drive, Suite 204 Orlando, Florida 32803 voice: (407) 384-9484 fax: (407) 384-9391 We thank you for purchasing Ami-Back, the premier hard disk backup utility for the Commodore Amiga personal computer. We hope you will find that it meets all of your backup needs. We have worked very hard to make Ami-Back the best backup utility available for the Amiga computer. Please let us know if you agree. Your suggestions and/or comments are most welcome. Unfortunately no matter how many times you proof read something, Murphy's Law will always prevail. We have a few minor corrections to the User's Manual. page ii -- CHANGE (9 am - 5 am...) TO (9 am - 5 pm...) We couldn't convince our tech support to stay this long. page 7 -- The "Novice User" options have been disabled during Ami-Back installation. page 26 -- The following should be inserted: Verify Mode In many instances you will wish to be certain of the data integrity of the backup Ami-Back is performing. In these situations it is recommended that you select the Standard option under Verify Mode. When this option is set to Standard during the backup, Ami-Back will completly re-read all the data actually written to the destination device and compare it to the data taken from the source device. In this manner, the program is able to verify whether or not the backup data is correctly written to the backup media and can be successfully re-read. Using the Standard Verify Mode will cause the backup to proceed at a slower rate. Depending on your destination device, this may take up to two times the normal time required to perform the backup. Setting this option to Compare will cause Ami-Back to compare the backup against the current filesystem in order to obtain a list of differences. Using the Compare option will assist you in determining if any files are missing or have been changed in any way. For tape users, the Compare option is recommended because some tape drives do not support the Standard verify command. Selecting Off for Verify mode will result in no verification of the data written during the backup process. Compression Ami-Back gives you the ability compress data during backup. This feature is especially useful if you are backing up to floppy disks, but there are also benefits to using it in backing up to other media such as SyQuest cartidges or tapes. When you select the Compression option, Ami-Back will check each file it encounters during the backup. If Ami-Back cannot achieve more than a 10% compression rate on the file, Ami-Back will backup the file without compression. This way, the backup is not slowed down for little gain. The amount of compression will vary depending on the nature of your data; however, on the average Ami-Back will achieve a 30%-40% compression rate. Because Ami-Back takes advantage of the Amiga's multitasking capabilities, you should notice very little, if any, speed loss during backups with the Compression option. In fact, if you are using an accelerated Amiga for backups to floppy disks, you will actually see that the backup is faster than without compression. This is because Ami-Back has to write significantly less data to disks. Include Sub-Dirs If the source device you have selected contains any subdirectories, you can choose to Include them in or Exclude them from the backup by using this option. For example, if you are backing up a device which contains two subdirectories and their corresponding .info files, selecting the Exclude gadget would instruct Ami-Back to ignore the subdirectories and back up only the two .info files. Set Archive Bit Setting the archive bit is necessary if you wish to perform a backup checking archive bits. Selecting the Yes gadget will direct Ami-Back to set the file archive protection bit for all the files included in the backup. AmigaDOS automatically clears the archive bit when a file has been altered so Ami-Back can tell which files have changed since the last backup. This option allows Ami-Back to detect whether or not your files have been backed up. page 71 -- Online Help is ONLY available when using Ami-Back20. It will not work with Ami-Back13. page 73 -- The Zoom Gadget will only work with Ami-Back20, and when using the WorkBench (type) Screen.
