This thread is really a plea for help, because I'm stuck:

My Amiga OS3.9 system has several partitions, ranging from 2GB to 18GB. On there I obviously have many files, often with very long file names, thanks to the SFS filing system. And I have been backing-up to removable HDs for some time, as this is the only sensible way to handle such large backups.


The problem I have is that my existing backup system has gradually become less & less usable, as the number of files has grown, as the total size of my backups has grown, and as my file names have become longer:

* LhA v1.38 (from 1992!) is the best I have, but it cannot handle backups larger than 1-2GB, so that I have to backup many folders individually (error prone). And I have severe doubts that it will handle long filenames properly, so since switching to SFS I have not used it.

* LhA v2.11 (from 2005) should have been way better, but it seems to be incredibly bugged, as it is unable to handle anywhere near the number of files that my backup requires (and which v1.38 handled fine). Plus the multi-archive feature is broken, so there is no chance of forcing it to generate backups composed of many 1 GB files.

* Simply copying the files directly onto my backup HD is not really an option, because (a) there is no compression (so I might run out of space), (b) there is no error checking (not a good thing for a backup), and (c) the backup HD uses a FAT or NTFS format (which would loose Amiga-specific stuff like comments), so that it can store Windows backups too.

* Currently I am saving an image of the entire Amiga HD, using a Windows program, but this is pretty crap because I can't restore individual files - only the entire Amiga HD.


So am I completely stuffed, or is there a fairly modern backup program which will handle such large backups, and which has long file name support?

I am using BackUp from onyxsoft to backup simplemail on my amigaone but I guess it is without compression.
Maybe if you could get your hand on diavolo ?

@lionstorm

My favorit is BackUp from Onyx...but maybe you need try Diavolo is more profesional and have more option!!

@ChrisH

Do you use WinUAE or Amithlon? Sounds like one of these. You could just format your external drive with SFS and do a

copy quiet clone dh0: dh1: #? all

where dh0 is your internal drive and dh1 the external one. That way you get an exact copy including original timestamp and all the protection bits. But indeed it is no "true" backup, just a copy of your data. Otherwise you should take a look at Diavolo, it is the best backup software the Amiga family has got.

Hi,

*hint* .. the latest lha is 2.12 .. maybe better for you .. ?

I use DiavoloBackup2000 on 68k with an DLT 40GB SCSI2 streamer ..
works .. good .. so long i need full restoring ..
Partial restoring is a problem because the DLT tape is only buggy
supported from DB2000 ... [support only ancient DAT tapes full.. no
DLT or OpenDLT or newer systems ]

A newer version from DB2000 with fixing the soft/hard-link bug i found
[the only bug that i found except the dlt problem] and with a list from
secure xpk packer libs [a couple of the libs i tested make no secure
backup, produce read errors on restore or hang DB2000 on restore full]
it would a taste of a back-up programm

And you can use lha with xpklzw*.libs too !

Diavolo Backup sounds nice, but I can only find a demo for v3 (not the newer(?) 2000). Plus neither AmigaKit or APC-TCP seem to stock it, so I'm not even sure if I can buy it. (((

If it proves impossible to buy, is there anyone who might be able to help me out privately?...

Diavolo with Tapestreamer is nice... though I've found it's more simple to just find a HDD big enough and copy all to it. No compression but who needs it with the cost of big HDD's today? Sure error detection would be nice but one can always run it over with DiskSalv if needed right? The best part is that it's so easy to do and so easy to extract individual files when needed. :)

Just a quick Google search lead me to http://www.vesalia.de/e_diavolo.htm as the first hit where it is available. Other dealers may also have it. If you have MorphOS on one of your machines you can also get it for free for that OS at http://diavolo.amigazeux.net/

@ChrisH

I'm old school me, and I and just make a Quarterback file of the partition I want to backup. You can choose how much compression to use - works for me, but then I'm not doing more than a few hundred megs at a time, so I can't say if it has size limitations.

I'm not using any BackUp software. I use a spare "twin" HD which i use to copy the partitions of my main HD to it. plain and simple.
Just FYI, lzx has a better compression than lha.

I don't like to order over the internet from a company I've never heard, especially if they are in another country. Has anyone ever heard of (or ordered from) Vesalia in Germany?

Plus £35 + British VAT + shipping is going to be quite steep for something I can't even get a demo of (although I suppose it might not be much different from the previous version).

Edit: It appears that the previous version (v3) can only handle harddrives of 4GB or under, which is no use to me, and so makes the v3 demo pretty useless

Vesalia is one of the oldest, biggest and most famous Amiga dealers in Germany. You can trust them, they are very reliable. But I know the shipping costs problem. This is why I do not order goods from your island as it gets too expensive for me. I once wanted to order a case that had no German distributor (it was even announced here as a special Amiga case) but shipping would have risen the price to about 2,5 times the price of the single case. Hopefully someone knows a British dealer that can sell you a Diavolo copy.

That's true, but doesn't lzx frequently corrupt large archives?
For example, LZX 1.21 corrupted archives of some ShapeShifter
hardfiles on my system. The test command will detect the bad
files, but it's not worth it to me to try to recompress files
after a failure.

I thought this was a known problem that had been discussed in
forums somewhere (couldn't find it just now, though).

Hi,

With DB2000 you will have THE best BackUp SW for AmigaOS ATM !
The programm is VERY nice and comfortable ..
Backup 40GB without no problem [over night with verify (~8h) ]
and is VERY save [except the problem with soft/hardlinks...].

It support the HW compressing from streamer [by DLT too ]
and archives full images from HD`s ..
It can use all kind of XPK packlibs [my favorite BZP2] and is
full multitasking.

I can only say --- buy it

@walter

I have version 1.21+ here [060 version 84996bytes] and i have no
problems .. the largest archive i maked was ~ 120MB

@ChrisH

Have you tried ABackup? You can find a freeware version on Aminet for download. I don't know if this suits you for what you want.

Hi, I have been using Diavolo since version 3, now using 2000. I normally do 1.5G uncompressed backups to a 4G QIC tape on a OS3.9 system. In all these years I lost just one file due to a medium failure.

You can do backups to SCSI tape, to a device (eg. DH17:) or to a single AmigaDOS file.

I am curious whether anybody around here used it with long filenames, which I never tried.

If you later decide for it, and use it on a Classic Amiga, you may also try my monitor program DiabloMonitor (aminet).

Bearing in mind that I want to backup selected folders of an SFS partition (rather than imaging the whole HD), and bearing in mind that I want my backup stored as several 1-2GB files (rather than to tape or other method), I have some
QUESTIONS FOR USERS OF DIAVOLO 2000:
* Can it backup files with names longer than 31 characters? You probably need SFS to have tested this.
* Will it automatically generate a new backup file(s) when the current one exceeds 1-2GB? I read that it asks for a new file name and/or disk, which is no good to me.
* Is it compatible with the (OS3.5+) TrueMultiAssign patch?
* Can it be made to ignore soft/hard links?

Thanks to R-Team for confirming that it can at least cope with 40GB on a tape drive. I just need to confirm that it will handle backups to multiple files now.

Hi,

@ChrisH

o.k. ... your answers :

YES it backup long file names .. use it on various SFS 68k last version partitions,
with long filenames .. one is my P2P partition [AmiGift/CTorrent] with max limit filenames !
[only in the GUI it have a few glitches by long filenames -- drawing the text
on the GUI bolder and dont update this gfx aera later]

From the V2000 readme you are right .. it "ask" for a new filename after ~2GB.
[have not tested this]

I dont know waht you mean by "compatible" with "truemultiassign" .. have this installed ..
but dont backup to a multiassign only ... [only all partitions]

partialy Yes, it can disabled "HL Dirs"/"HL Files" to backup .. SL always backuped ..
the Bug with HL/SL is :
If you have Dir AND File Links in the same directory and in the DB2000 file-lister
[also for DB2000] both come one behind the other .. the backup with commpression or/and
encrypt libs will maybe corrupt !
To avoid this you can make no dir and file-links in the same dir [he,he .. smart ]
or place a dummy file [i use 0 byte files] between the dirs and files.Then it works.

The max backup size is 2TB
It used the OS3.5+ style for >4GB HD´s [NSDPatch] and TD64 [P5]
It can use alternate floppy controler [catweasel]

Hi,

with support from the new OS4 DOS API >4GB files and nearly actuall
tape systems [dont need the last high end 8TB tape library ],
as OS4 native version [and with fixing the links bug ..] this would become
the standard back-up OS4 software ...... ....

[...] an OS4 native version [of Diavolo]

I don't think this will come anytime soon : Amigazeux got the sources (and released the MOS version) but they don't have OS4 nor they have interest in it so I doubt they will ever produce an AOS4 version, however may be if they have enough query for a 68k one... (Amigazeux's version seems to correct some bugs, so will always be good to see a 68k version we could use on OS4)
