Synthetic full I/O patterns need to be split into two different operation: the creation of the additional incremental is exactly like any other incremental job.
08.06.2021 · To create a synthetic full backup, Veeam Backup & Replication performs the following steps: On a day when synthetic full backup is scheduled, Veeam Backup & Replication triggers a new backup job session. During this session, Veeam Backup & Replication first performs incremental backup in a regular manner and adds a new incremental backup file to …
04.04.2020 · Forever forward incremental is 3 I/Os per backup on the repository because on every backup a merge process takes place to combine the full backup file (.VBK) with the oldest incremental file (.VIB). The same is true for reverse incremental. The only difference is that the VBK in reverse incremental is always your latest recovery point, allowing ...
12.04.2016 · Forward incremental can now operate with only 1 full backup on disk – so there is a chance that you don’t need to do synthetic or active full backups; so that is good also. To make a specific recommendation on what mode is best, depends on where you are putting your backups (storage system wise), your retention requirements, and “what else” is going on with that …

We don't plan to have very long chains, probably about 7 restore points, so I imagine forever forward incrementals would be okay. I was just worried of the I/O impact when the retention is reached and the full and incremental are merged vs synthetic backups.
Solution: On my file server(s), what I do is set a retention for 35 days using Incremental backups. Each weekend Veeam automatically does a "Synthetic Full"
12.10.2012 · 4. When job finishes, synthetic full is disabled again. This script can be scheduled via Windows Scheduler to run once every two weeks, or once a month. However, for the purpose of backup chain safety, I’d recommend running this script every two weeks, with monthly active full backup option being enabled. Hope this helps.
Forever forward incremental method keeps one full backup file (VBK) on disk, and then only incremental backups (VIBs) afterwards. This method allows backups ...
It would be recommended that you do your forever incrementals, but also have it do active fulls, periodically. I wouldn't call myself an expert w/ veeam, but the way it was explained to me is that when doing the synthetic full, it uses the chain of incremental to build the full backup.
The forever forward incremental backup method produces a backup chain that consists of ... If you enable synthetic and/or active full backups, Veeam Backup ...
