cPanel & WHM Version 80 has been released, and brings a slew of great updates. Take a look at what is included, and then upgrade today!
 

Backups: Wait until account backup is finished uploading, and removed, before backing up next account.

Open Discussion

As a server administrator, I would like the backup system to create and upload a single backup at a time, preventing my server's disk space from filling up while waiting for the backups to complete and upload.


===========

In the Legacy backup system, an account would be backed up, uploaded to the FTP location, and removed from the local server, before the next account was backed up. However, on the new system, it starts backing up the next account(s) while the previous account is still uploading.


Because of this, a server will potentially need more free space in the new backup system, than it did in Legacy, to backup their accounts. Switching from Legacy to the new system may result in the disk running out of space during backups, when it wasn't previously.


I request an option to force the new backup system to wait for a backup to finish uploading, and being removed from the local server, before backing up the next account.

Hey folks. In talking with our dev team it seems like the only remote destination that is currently hitting this delay is FTP uploads. The others are queueing properly, and immediately uploading as we want them to. We've got an internal case open for it, but I've also opened a feature request that specifically addresses that one.

https://features.cpanel.net/topic/queue-backups-for-upload-to-ftp-destinations

Because the requests I merged together here were all 'Create and upload one backup at a time' I don't want to merge these into the one I created, but I am hoping that once we get that addressed this won't be a common situation that gets encountered anymore. If you believe that a faster queueing might help you as well, please go vote on that one as well. If you have any other questions or concerns, you know how to find me!

I would like further discussion and feedback on this matter. I can see the argument to the contrary here in that there may be server admins more concerned with backup availability (versus disk space consumption) who would be willing to expend the disk space to ensure that day's backups generated as quickly as possible locally. This leaves the less intensive transfer process to occur "last" and potentially reduce performance impact to customers as peak hours start to ramp up.


Therefore, I'd like to get a better feel for the opinion on this with more feedback/discussion.

But still you can add limit on keep generating backup on local server unless previous files transferred to destination.


Example: I added limit of 10 accounts so WHM can't generate backup of more than 10 accounts. WHM generated backup of 10 accounts and then stop generating new backup unless 1 backup send to the destination. Once 1 file is sent, Only 9 backup files are left so again WHM will start generating backup of 1 account to make it reach 10 account backup limits.

(Hope you understand what I am saying, By this method backup will be not slowdown.)


(Currently I am using this method with 5 maximum backup using my custom script but many providers who don't have 2TB to 10TB extra disk can be saved from this hassle)

I think it's best to have both options available: one for those with lots of diskspace and one for those with less. The WHM interface could have a radiobox with "pack and upload accounts one by one" or "pack and upload all accounts simultaneously".

Please make this feature, it's painful; specially for SSD VPS.

Is there any progress on this? The potential for the backup destination being unavailable for whatever reason means that backups would pile up and take up potentially exponentially more space in comparison to zipping the next account while the first account uploads and then waiting for said upload to complete.

We are facing this issue again with our small-capacity SSD server. We really need the one-at-a-time option. This is the only missing thing that will make the new backup system perfect.

I have the same problem, in my case, my all accounts of my server were used 60GB disk space and my free disk space was only 40GB, if I enabled the WHM Backup status and I disabled the "Retain backups in the default backup directory" option and I used a retmote FTP server as my storage, it should be able to work but it will always backup fails! It seems to wait for all the backup files stored in the /backup later, then it will start uploading to the remote FTP server, If so my available disk space must be always greater then used disk space, I think this is a wrong design, especially for VPS servers because usually SSD disk is very expensive, is it possible to be able to make the process one by one backup and upload then delete then continue next backup process?

I agree with your statement. To speed up whole thing I think that currently simultaneously pack and upload is acceptable option for everyone but only missing one additional feature, to temporary pause backup generation if there is not enough free space left (lets define this at 5% free space left). After existing packed archivers are transferred to the remote location to free up some space on the local server continue with generating backup archives where they are paused before.

I prefer the current method for the reasons stated by cPanelBrianO, but it would certainly be nice to have both options.

I'm currently having this exact problem in a VPS that doesn't have alot of free space. This should be configurable.

I would also love to have the option of restricting the number of account zip files created during backup. A simple toggle for single threaded ZIP generations and FTP transport would be fine but a more complex solution that would generate more ZIPs for transport if there was enough space would also be welcome.


Came here from https://forums.cpanel.net/threads/single-threaded-backup-transport.595495/


Thanks!

I strongly recommend adding this feature as well. I run high performance SSD VPS, where diskspace is a pretty scarce resource. I really hate to waste it on having overhead for backups. Additionally, while I can understand your argument for getting the backups done, then transferring, so that the painful time while the backups are generated is minimized, I also see this feature as a way to generate the account, then give the server a break while transferring it, generate, send, over and over. I'd also suggest that if we could have a way to throttle the bandwidth. For me, cPanel backups would be a secondary backup, so I don't mind if they take a while to send. As long as a server is fully backed up in 24 hours, and doesn't exceed that, I am happy for secondary backups. Now primary, I want that done as quickly as possible.

With theremote incremental backup, this means that the local files are not compressbefore being sent out. Therefore, we have to reserve almost 50% of the drivefor incremental backup.

Personally,I don’t mind having more bandwidth for backup since there are sent on a backup serverconnected to an internal 10gbs switch and won’t affect our client traffic.

In general, SSD servers don't have a lot of free space. I think it's an important feature.

Or add option in backup configuration setting to backup/upload accounts one by one or all at same time.

It's especially handy for remote destination like FTP.

I think thsi would be a great feature for people who don't have lot's of room to store backps

sftp don't upload straight away sometimes it can do 30 plus backups then send to remote server ?
