EXTREMELY IMPORTANT: Please attach a ZIP file containing your Akeeba Backup log file in order for us to help you with any backup or restoration issue. If the file is over 10MiB, please upload it on your server and post a link to it.

A few months ago I set my backup to go to BackBlaze; it always goes in 40+ different parts. 

I would like to back up and download as 1 file.

What do I need to change to get it in just 1 part and saved to my server on Joomla so I can download?

 

Thanks

Ok, I have seen the other posts about NOT downloading as one large file.

But is there a link that shows me (if needed) use the 40+ parts to reload the file in case I need to upload the site? I seem to be missing that part.

 

Thanks

General guidelines for backing up and restoring your site under “Multipart backup archives”.

Using Akeeba Kickstart also tells you to upload all of the files.

Preparing for the extraction in Kickstart's documentation.

You're welcome!

And for anyone hitting this ticket looking for the solution: Upload all part files (.j01, .j02, …, .jpa). Upload Kickstart. Run Kickstart. Select the .jpa file (only thing listed). Kickstart finds all the archive parts automatically.

This is great and answers my questions completely, so thank you!

Question: I reset my Akeeba backups to go to Backblaze like I had before (in smaller parts) but when I backed up this morning, it seems it is going on one large file, instead of the several parts you recommended.

May I ask what I didn't set correctly?

I am attaching my log file and a screen shot.

Thanks for a great software and great support.

The setting you need to check is Part Size For Split Archives under the Archiver Engine options.

This setting is per backup profile. If you changed it in one profile it does not apply to other profiles.

Moreover, if you restored your site from a previous backup which predates your change then, of course, the change is rolled back: restoring a backup restores the database contents, which includes the backup profile configuration (the #__ak_profiles table).

Thank you.

I've attached a screenshot of my setting, which I thought was what I had previously when it was splitting the archives.

Do these look correct to you?

It's hard for me to answer. All I can tell you is that for whichever backup profile this screenshot refers to, the part size is 2047MiB. Any backup smaller than this will be a single file.

The only other ticket you have filed under your user account does not talk about split archives at all. Since we had not discussed this setting previously, I don't know what it was set to in the past. I can infer that it probably wasn't 2047 MiB because a 40+ part archive with this part size would be 80+ GiB — I think you'd have told me upfront if you had such a gigantic backup archive, right?

Conversely, since you have a split backup archive check what is the size of the .j01 file. That's the first part file of the backup set (.jpa is the last). The size of the .j01 file is the part size you had set up. Make sure to divide the size in bytes with 1,048,576 to come up with the value in MiB. Note that Windows and macOS (and some Linux desktop environments) use base-10 megabytes (1,000,000 bytes in 1 MB) instead of base-2 megabytes (1,048,576 bytes in 1 MiB). Akeeba Backup uses base-2 megabytes.

Thanks, Nicholas.

I look at my previous backups on BackBlaze and the files are 21 MB. So am I OK to set the file size to 20 MB? I've enclosed a screenshot so you can see.

Much thanks

Correct. You can set the part size to 20 MB.
