How to merge splitted back-up archives into 1 back-up file?? (ATI 2011)

Thread needs solution

Hello there,

Due the fact I can't even reach the support center via e-mail and because there's no Dutch support, I'll try it via this way: the forums.

I made a back-up of a 170GB big folder full of video files on a 165GB big internal hard drive partition (D:). I hoped the final back-up would be smaller cause of the 'high compression' option. But this wasn't the result. It splitted my back-up into 2 parts automatically and then a third time manually on my C: drive.

So I made my C: drive smaller and my D: drive bigger up to 180GB and then copied the third part of that same back-up from my C: to D: drive where the other 2 parts were.

Now I have 1 back-up splitted into 3 archives and I want to merge them into 1 big backup file as it normally should be after making a backup, how can I do this?

Thank you,
Bart

Because video files are typically already compressed, most of the time very efficiently, you won't gain anything at using ATI compression. On the contrary, you might INCREASE the space needed.
If you don't use any compression, you will get a bigger file anyway because of the internal information ATI adds to the data being backed up. So leave it at normal compression and you should be getting about the same size as the data being backed up.

You know, using ATI to backup video files is not the best approach. For big files, using already compressed formats, some sync software is the best approach (eg: Karen's replicator, SyncToy, SyncBackSE, ATI 2012, ...). I'd recommend one that can verify the copies it makes and can keep versions if anything happens to the file. I personally use SyncBackSE.

To answer your question, I wouln't bother trying to consolidate the files. There is a consolidation feature in ATI but it needs a lot of space, is as lenghty as a new backup, and can fail.

I didn't know video files cannot be compressed anymore sufficiantly. Thanks for saying that! At least it's 1GB smaller than before :p

I didn't know either an other way to back-up those videos, but I don't understand the concept of those sync-software programs... Is it like synchronizing your MP3's to your iPod? Cuz that goed amazingly fast for 16GB :O !!

And how would you do such consolidation in ATI if it's possible? :)

Glad to hear! Your mileage will vary...

Yes, sync software typically create a copy of your folders on another disk/computer/server and keep it up to date. Some software move the deleted files or old versions to a holding folder for a while.
Of course ATI is pretty good at backing up files, and event better at backing up partitions. But you need ATI to restore the files. If your big container gets corrupted, you lose ALL what is inside. Corruption happens. When it happen, you can, last resort, reinstall your OS, your apps, buy back your music and movies, but you won't get back your personal pictures and movies... BTW, to be clear, this is nothing special about Acronis. Any backup software that stores info in proprietary formats present the same risk. BTW2, in a file backup, you can instruct ATI to store the backup in a ZIP file (not proprietary if you don't encrypt).

And how would you do such consolidation in ATI if it's possible? :)

Consolidation works only for several versions of a backup, done at different time. This doesn't work for size-split backups. It doesn't work on backups files done or identified as separate tasks by ATI.
For consolidation to work, you need 2 things:
- all the backup files need to be identified by ATi as part of the same backup task (they don't show separately in the ATI UI, but they all show up when you click on explore/recover).
- you have enough space on the disk where the files are to accomodate a copy of the biggest file you consolidate with a 20% margin or about.
Then, click on "operations" > "more" > "consolidate versions"
