Please look at the bottom of this page (under Support Policy Summary) for our support policy summary, containing important information regarding our working hours and our support policy. Thank you!


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 2Mb, please upload it on your server and post a link to it.


Description of my issue:

Our host recently upgraded our webserver from Linux Mint18 with php 7.0.3 to Mint 20 with php 7.4.

Our Akeeba backup is running and seems to be working fine but the backup is now taking 4 times as long, the management page says they are basically the sale size, aprox 2 gig jpa single file but are taking over 2 hours where previously the backup took more like 30 or 40 minutes.

I have used Admin Tools to check and optimize the tables, no real change

The admin at the host is trying to be helpful but does not really know why it is running slow. I don;t think it's Akeeba but thought you might have a suggestion of where we might start looking for the answer.

Thanks in advance, I understand this is probably not your problem but thought you might point me in a direction.

It's not a problem with Akeeba Backup or PHP. Akeeba Backup 8 is actually a little bit faster than Akeeba Backup 6. PHP 7.4 is much faster than PHP 7.0. Moreover, even if you were to go the opposite direction (from Akeeba Backup 8 on PHP 7.4 to Akeeba Backup 6 on PHP 7.0) you'd notice about 15% to 20% slowing down of your backups, not well over 300%.

There are only two things which can justify such a massive difference.

One issue can be the network egress speed if you're using remote file storage for the backups. However, this doesn't apply to you since your backups are locally stored.

The issue that applies to you is the server's I/O throughput. Remember that dumping the database and taking a copy of all of your sites' files is a disk I/O intensive process. Your host needs to check whether they make any changes during the update which could have made disk I/O slower or resulted in much more disk I/O. This can be something as setting the atime flag on mounts to reducing the memory caching. They should know their setup better than either you or me do :)
