Ami-FileSafe (AFS)<br />
<br />
Upgrade your Amiga's performance and reliability with new system software<br />
-- replace FFS with a faster, high data-integrity filesystem. With<br />
Ami-FileSafe (AFS), your directory listings will be smoothly displayed, and<br />
software accessing the disk will run faster. More importantly, AFS ensures<br />
your data is safe from invalidation caused by machine crashes and<br />
accidental reboots. AFS is always validated -- you will never have to put<br />
up with invalid disks again. The consumer version is limited to one 650mb<br />
(or smaller) HD. The professional version, perfect for video and audio and<br />
other intensive use, includes support for HDs to 9gigs and multi-user<br />
security.<br />
<br />
Independent tests reported by CU/Amiga magazine show AFS using 7-11% less<br />
disk space, with write times up to six times faster, and read times up to<br />
twice as fast as the best previous file systems. CU/Amiga tested AFS<br />
reliability by resetting, powering down and removing SCSI cables while<br />
writing to the drives. "Not once through all these heinous eye watering<br />
tests could we corrupt the AFS partitions!"<br />
<br />
US list prices are: Consumer $40, Professional $99.95.<br />
<br />
AFS FAQ, 03-OCT-95<br />
<br />
Ami-FileSafe (AFS) has generated enormous interest. The purpose of this<br />
FAQ is to answer the questions we've heard many times, and to provide you<br />
with more information about AFS. This FAQ was prepared by Dale L. Larson,<br />
el Presidente of Intangible Assets Manufacturing (http://www.iam.com). It<br />
is accurate to the best of his knowledge at this time, but AFS is a new<br />
product to IAM, and it is a sophisticated piece of software. This is the<br />
first preliminary edition of the FAQ, so it is subject to change, we<br />
disclaim responsibility for any errors and lies, etc.<br />
<br />
Q: When/Where can I get AFS?<br />
<br />
A: AFS is published and supported by Fourth Level Development. Intangible<br />
Assets Manufacturing (IAM) is the exclusive distributor for North America<br />
(While FLD is the exclusive distributor for IAM products in Europe). IAM<br />
makes AFS available through Amiga dis tributors and dealers (both local and<br />
mail-order), as well as direct (i.e., mail order). IAM received its first<br />
major shipment of product earlier this week, and shipments were sent to<br />
many dealers immediately. So if your dealer doesn't stock it, ask her to!<br />

<br />
Q: What is the current version of AFS?<br />
<br />
A: 2.2.<br />
<br />
Q: How much is AFS?<br />
<br />
A: There are two versions. AFS Consumer (also called AFS User) is US$40,<br />
AFS Pro is US$99.95.<br />
<br />
Q: What are the limitations of the Consumer version?<br />
<br />
A: The Consumer version can only be installed to a single partition, and<br />
that partition must be on a drive which is less than 650mb capacity (not a<br />
partition of 650mb, a drive size of 650mb). You cannot install Consumer<br />
onto a 10mb partition of a 700mb disk . You may have other drives and<br />
other partitions in your system. The Consumer version also contains no<br />
multi-user support.<br />
<br />
Q: Why are those limitations in Consumer?<br />
<br />
A: This is basically a marketing decision, but one which is forced on us. <br />
AFS is a highly technical product which requires a great deal of<br />
development resources. We cannot support those resources with sales of<br />
User alone. So we selected limitations on User that would allow those who<br />
truly cannot afford Pro (and who do not need multi-user support, which was<br />
also expensive to develop) to get use of AFS User, but require those with<br />
more sophisticated systems to buy Pro, paying a fair price for the<br />
software. Note that the benefits of AFS go up with the size of your<br />
harddrive -- a 1gig drive takes much longer to validate than a 200meg<br />
drive!<br />
<br />
Q: What is the policy to upgrade from the User/Consumer version to the Pro<br />
version?<br />
<br />
A: In the US, the cost of the upgrade is the cost of the difference in<br />
price plus $10 ($70). You must send in your original disk with payment,<br />
then you will be mailed a new Pro disk. This process should take about<br />
7-10 days, but is unavoidable due to serial numbers, etc.<br />
<br />
Q: Where can I read an independent review of AFS?<br />
<br />
A: Dave and Dale both say AFS is cool, so what more do you want to know? <br />
For you doubters, the September 1995 CU/Amiga did a two-page review, Amiga<br />
Computing has a review in their October 1995 issue, and other reviews are<br />
being written. Since AFS is evolving fast and magazine reviewers often<br />
look at a product more than four months before an issue gets to<br />
subscribers, most of the limitations found by reviewers have already been<br />
addressed.<br />
<br />
Q: When will DiskSalv3 understand AFS?<br />
<br />
A: Dave is working hard on this support, and has been doing so throughout<br />
the summer. We expect to be shipping something by January of 1996.<br />
(Please note that earlier dates which have been publicly announced did not<br />
come from Dave or IAM -- this is IAM's first public statement on the<br />
subject.)<br />
<br />
Q: What is the policy to upgrade DiskSalv3 to AFS-supporting?<br />
<br />
A: IAM's commitment to the Amiga is clear -- DiskSalv3 has been upgraded<br />
through four freely redistributable patches during the last year (the<br />
current version being 12.19). The upgrade to support AFS will probably not<br />
be a freely redistributable patch. However, it is our intent to ensure<br />
that loyal customers of DS3 are well-treated, and that you will get a<br />
better a deal if you buy DS3 now and upgrade later than if you put off your<br />
DS3 purchase.<br />
<br />
Q: What about ReOrg?<br />
<br />
A: Yeah, we will take care of that one specifically, and a few other tools,<br />
too. We aren't ready to announce the details yet, so please don't ask, but<br />
we plan to make an announcement in the next month or two.<br />
<br />
Q: What's this about AFS Floppy?<br />
<br />
A: There is a floppy-only version of AFS. It is unlikely to be released as<br />
a stand-alone commercial product, but you may get it bundled with other<br />
products. For those of you with floppy-only systems, or those who want to<br />
try AFS on floppies, this is an excel lent bargain. MegaBall4, the new<br />
game from IAM, will include AFS Floppy as a free bonus disk!<br />
<br />
Q: Is there a demo?<br />
<br />
A: Yes, there is a demo version of AFS which can be installed to a very<br />
small partition to give you a sense for whether you want to buy the<br />
commercial product. The demo isn't always available in the same revision<br />
as the currently shipping AFS (right now it's demo 2.1, production 2.2),<br />
since obvious ly it is the lowest priority of the four versions. An older<br />
version demo was on a recent cover disk. IAM has no more information on<br />
where to get a demo at this time, but we'll put one on our FTP server when<br />
we get one.<br />
<br />
Q: Will AFS work with removable media like Zip and SyQuest drives?<br />
<br />
A: Yes. The Consumer version will work, too, as long as those drives are<br />
the only one AFS is on and the drives have less than 650mb capacity (which<br />
is the case for all current models). Fourth Level Development has special<br />
removable media support tools which they bundle with drives. These<br />
packages are not yet available in the States, but we are aware of the<br />
demand. Without that software, you have to do the same thing you would<br />
with FFS on removable media -- HDToolbox, etc.<br />
<br />
Q: How reliable is AFS?<br />
<br />
A: It's pretty darn reliable. Read the magazine reviews. September's<br />
CU/Amiga said "AFS doesn't invalidate disks. During the course of our<br />
tests we reset whilst writing files, powered down when the buffers were<br />
being flushed and pulled the SCSI cable out of the drives. This is just<br />
asking for trouble, but not once through all these heinous eye watering<br />
test could we corrupt the AFS partitions!"<br />
<br />
That should be good enough for most people, but here is a little more<br />
detailed and technical information...<br />
<br />
FLD says "AFS has been written to take advantage of the atomic theory<br />
of filsystem construction. This means that no data pointers are changed<br />
unless the validity of the data at which it is to be pointed has been<br />
checked as far as is practically possible. AFS has been written to take<br />
advantage of the basic physical features of all hard drives. In<br />
particular, the amount of time which is taken for capacitance levels to<br />
drop in the event of a power outage to the extent that data can be<br />
corrupted.<br />
<br />
Both the MaxTransfer and the DMA mask need to be properly set to ensure<br />
that the maximum integrety is obtained from the system. The AFS<br />
documentation includes detailed information on how to set them. For<br />
systems that follow these guides, FLD is aware of no instances of data<br />
loss with AFS since pre-release version 14.7. The system has been<br />
exhaustively tested by independent evaluators, none of whom have<br />
experienced data loss. Any bug reports made to FLD are carefully tracked<br />
and treated.<br />
<br />
In the event of memory corruption, the only known result has been the<br />
loss of data within individual files or directories which have been<br />
caused in consequence of programs corrupting memory.<br />
<br />
In the event of an attempt to corrupt the filesystem cache, AFS converts<br />
the filesystem to read-only, protecting your precious data.<br />
<br />
With pre-release/beta version 14.3, there existed known and documented<br />
limitations with the use of some software. Those limitations were fixed<br />
before the release of AFS, but unfortunately, someone who had been sent<br />
the beta version used some of the software on the list not to use, ran<br />
into problems, and posted that they had caused corruption on an AFS drive."<br />
<br />
As someone who gets a lot of calls from OFS/FFS users desperate for<br />
DiskSalv3, I KNOW what kind of data loss you can get from the standard OS<br />
filesystems. And how crippling invalidation can be.<br />
<br />
I can also say that nothing is completely safe, which is why everyone<br />
should make regular backups, regardless of the filesystem that they use.<br />
