Just wondering what everyone uses (or IF you bother) for backup on os4?

Do any of the old Amiga solutions work, Quarterback Tools for example.

The only idea I've seen so far is cd or DVD, but since my drive is around 250gb that would be cumbersome and time consuming.

I also tried making a 20gig lha file but it would not work (file systTem limit?)
, copying to a fat 32 USB drive loses all the protection bits.

What are other os4 users doing to preserve their data?

@danwood

Do you try BackUp ?

Not seen that before, but from the docs it seems it's little more than copy #? All

This still begs the question of where you copy the files to.

On the subject of backup, is there an Rsync port available? Rsync is an awesome backup tool, for both copying onto (say) USB attached disks and copying over the network.

Too a second bootable HD of course, using Backup.

If the main drive goes, I have a bootable backup to fall back on. Even a second bootable partition with one drive should work. There are no apps to save your butt, thats why I have 2 HDs.

If you save your files over several partition then it is easier.

I use 3 partitions for Amiga specific stuff. These I back up each to an .iso file using AmiDVD . None are 4.5GB yet .The .iso files I save to a dual drive external USB hard drive formated in fat32. I also keep PC backups in Arconis backup format on this drive

SYS:
Programs:
Data:

Then

Work:
Media:

Work I dont backup.
Media for Video's picture MP3's etc I backp to the secod drive on the external USB drive as single files in folders of just under 25GB .

I can then use a PC with a Bluray burner to backup each folders of just under 25GB per disk .

The external USB drive also has ESATA so this would be an option although the SAM 440ep-flex Sata port will only recognise the first drive and needs it to be an Amiga file system. Both drives are recognised by Amiga OS using USB and Fat32 format.

For some very important file like my business accounts I also mirror daily on to a PC via Samba and a 68k program called Archive.

It's a bit more than a simple copy operation.
It's a very good incremental back up tool.
How about 35seconds to back up a 5GB partition.

Short: A simple backup tool.. v1.71 UpLoader: Daniel Westerberg (daniel@onyxsoft.se) Author: Daniel Westerberg Version: 1.71 Type: disk/bakup Architecture: m68k-amigaos >= 2.0.4 This is a simple backup tool with a few useful features. It simply copies files and links from one directory to another. Of cource it only copies files that are different in some way, like size or date etc. So the backup is incremental. Features ~~~~~~~~ - Very easy to use GUI. - Backup from one directory to another directory. - Very fast and copies only what needs to be copied. - Copies files and directories as they are, does not store in some custom backup format. - Can be used from the boot shell without any libraries installed. - Copy softlinks as softlinks by recreating the softlinks on the target. - Copy softlinks by following the links and copy the files and directories. - Ignore all links completly, including hardlinks. - Specify sub-directories that should be excluded from the backup. - Specify large individual files (over 512kB) that should be excluded from the backup. - Specify a maximum file size of files to be copied. - Clean the backup from old, previously backed up files that have been removed from the source. - Can be paused or aborted. - Can be executed from scripts including all features normally controlled through the GUI. - Can backup based only on the archive protection bit. *** This program has been successfully tested on AmigaOS 4.1

Update...

I have 4 partitions plus a small FFS2 partition for backing up important files.

My backup scheme since AmigaOS 4.1 Update 1 was ....
AmigaOS 4.1 Update 1 on CD-R
All further upgrades done by download, unarchive and install
Routinely backup important files to my Backup partition and USB sticks

This evening, I made a recovery CD for my current AmigaOS 4.1 Update 5 system.

I used AmiDVD to backup my SYS: partition to an iso image and burned to a CD-R disc.

My SYS: partition is very small and easily fit on a single CD-R disc.


For backing up files to another partition or another hard drive, I recommend the BackUp program already mentioned in another post.

Edit ...
I suddenly realized that Update 1 was the iso image and updates 2 to 5 were updates.
I made a recovery CD for update 2 and update 3, but not update 4.

My back upping is a little bit in bad shape.
I have 1TB drive in our home LAN, I plan to use it more in the future.

I could mount it as a drive with ftpmount or with samba.
Then I think folder sync might be the bets PPC native tool to have files safely in two places?

Actually, that way I should be able to sync the same (data) files to every household Amiga, I think.

For SYS partition... as it mainly contains SW binaries it is pretty small. I can copy it's content to work:AOS4BU/ and then folder sync would dublipcate (triplicate) also that.


On 68k I have used Abackup (I think). It was very reliable and far better than for example M$ standards. But I have not tested if it works reliably on PPC.
Someone should test thoroughly all those 68k backup apps on PPC.

@danwood

Yep, it might be simple but it works really well, and with the bonuses of being very fast (no compression / tarballing of files), and being able to simply browse the backup without needing any special software. It only copies what's new or changes, and has the option of removing files from the backup that no longer exist on the primary drive.

As for where to, I do a backup frequently to a second internal hard drive, and then from time to time some critical files to my NAS. Occasionally I also do an .lha file of the critical stuff and stick it on a DVD, but that's a little more involved...

Of course doing a backup on a different partition on the same disk is quite useless in case of hardware faults
I can't stress enough how buying a NAS was one of the better investments in my IT-life not to mention the advantage that it's visible from all my devices: Amiga, PC, PS3...

I recently found the hard way why you should rely on backup backing up one mounted disk to a second mounted disk after a single lockup taking out the data on both disks.

OS4.1 has no way of checking/reparing SFS2 partitions so my backups for my programs and my systems disk were both whipped out at the same time

I guess I should have been making backups to a removable or non mounted disk but USB always dropped out on my sam440ep on update 2 and 3 before could finish making a backup normally corrupting the disk so I stopped trying to backup that may.

With update 4 and 5 USB seems much more reliable so I will try backing up to a USB disk again and see how I get on.

In the passed I have just used dopus to make a copy of all my files to a new location, but as the simple backup tool in talked about here looks like a better solution I will have to give it a go

@Dwyloc

IIRC, before backupping to USB, be aware that you may hit 2GB or 4GB barrier. For me USB backup drive (WesternDigital) is pretty useless because it uses some old FAT filesystem.

With some tool like ABackup I think one can split the backup automatically, for example, to 700MB pieces. But I have not tested that SW far enough to rely on it on NG system.

@danwood

Abackup, Quarterback and Diabolo, only works on FFS and partitions under 4Gb, so I make an ISO image with MakeCD and burn a DVD or two.

@KimmoK

This ABackup and other old tools sound dangerous since they seem to create some inaccessible custom backup format that you can't access when the time comes and you really need it.

The modern way is to make pure file copies without compression or bundling of files into blobs. This way only the file system sets the size limit, not the tool. BackUp does just that and there are two reasons why this is the best:

1. Modern backup media is very very large, so no need for compression to save a few percent of disk space.

2. Material that really does benefit from compression, like audio and video, is already highly compressed and cannot be compressed anymore, so why waste the time and obfuscate the files without any gain.

@danwood

I'm not using exactly OS4, but on all of my Amiga systems I use backuping to external USB storage which is SFS formatted (to preserve Amiga's file attributes). Mostly to just "copy all clone quiet" and BackUp. And I keep certain states of system backed up to different directories, so that I can restore some older stuff too if needed.

Years ago I also used Diavolo with DATs and external HD:s etc, but as USB and CF etc systems are big, cheap and easy enough nowadays I've practically moved fully to them. Keeping stuff unpacked on Amiga compatible filesystem is just perfectly easy to restore and backup.

I am looking for a good way to backup stuff, so I found this thread.

I looked at Backup but I need a way to verify the backedup files, and I dont think Backup does that.

Also compression is not needed as stated in this thread as I want to back it up to another (removable) HD

Thanks

it can! in the current version you can do a byte-by-byte verify after backing up!
quote from the readme:
Quote:

1.90 (141022) ** Added a verify byte-by-byte function in the Misc menu. Useful to test if a backup is truly perfect, or if it has bit errors.

then backup is the perfect solution!

I use backup tool from deniil to backup to my sfsformated usb 32gb stick. All my 3 partitions fits as i dont have much mediafiles like movies etc.

Funny this thread has been brought up again, as I'm currently in need of a backup solution for my A4000 (3.9), the idea above about external USB is nice (I have a rapid road), guess it would take a while but easier than starting over should anything go wrong.

EDIT: I see the Backup tool mentioned earlier works on OS3, so will give it a try.
