Cloud backup spontaneous LARGE incremental backup.
We had an issue earlier this year with ati 2019 .. daily cloud backups had been working fine with small incremental daily backups for a few weeks, then suddenly it appeared as if ati2019 cloud decided to perform a fresh FULL system backup again. It acted like incremental, but the size matched a full new backup of the entire c drive (500+gb) and it took a few days to process. We thought this was a fluke so we erased cloud backups and rebuilt them. And a month or so later it happened again. This causes us to run out of cloud storage space before it can complete, and it slows down our internet and computers for a few days, and we get warnings from our ISP about data caps exceeding. We last had the issue around feb 2019. We stopped using cloud backups because of it.
Does anyone else see ati2019 cloud backups suddenly perform a large backup?
Joe, I have not seen any backups to the Cloud that trigger what would look like a new full backup upload unless there has been a significant large change to my computer, i.e. new Windows Insiders build installed or major Windows Update such as the October one last year, but again the size is not equivalent to a new full backup.
Same for me as Steve. Major Windows updates change the partitions of the disk, resulting in disk ID changes which can trigger a large incremental - that might be the biggest killer, and potential issue with a full OS backup to the cloud
I'm not backing up a full disk (OS) to cloud anymore either. I have one backup for my user profile and one for an off-site of my photos. I'm doing local backups (one to an internal disk, one to USB and one to NAS) for everything and using cloud as my off-sit, just in case for critical data if all of my locals go up in flames.
Another possibility is that the disk drive has been fragmented; Acronis Cloud backups are block based, and defragging shits content to different blocks. All my systems use SSD which are not defragmented (trimming does not change the blocks in which data is located). However, I doubt that the removing file fragmentation would have such a big impact.
sorry everyone for the slow response. I was on vacation. The drives in question are actually ssd, so I don't think it is the defrag option. But I do think it might be the major windows update. I am backing up to the cloud by selecting partitions. Perhaps partition backup method is more prone to re-backing up all when there is a windows update. Does anyone feel if i should change the backup type to entire pc, or file only? When it does the really large incremental i think it was after a major windows update, and i think the incremental size was pretty close to the size of the entire disk.
Joe, as far as I am aware, there should be no difference in backing up to the Cloud by selecting partitions or selecting either the entire PC or individual disks (and their partitions).
Major Windows Updates can cause a lot of changes to the OS drive but shouldn't result in causing an incremental size similar to the size of the entire drive unless there is something else going on here?
I would recommend using the MVP Log Viewer tool (link below) and checking the actual Cloud backup log for the oversized backup upload to see if that offers any clues as to what happened?
