Hi team, I'm trying to figure this out. Dr. Paes is still experiencing remote connection issues, and the Nova Backup is running a backup_remote scheduled to run daily. Does that mean his bandwidth is not enough to complete the daily backups, and he would need an upgrade?

Because they recently upgraded the server, a full backup has to take place. Their data size is over 1 TB therefore it takes several days to complete. After that daily changes take only few minutes during the night. For 99% of clients the initial backup does not cause these slow connection issues, so judging by persistence of this issue they may need to upgrade their internet.

Hi Alex, thanks for clarifying. What would be the recommended internet speed? With the current internet speed, this should be done by next Monday right? Pending gb: 1017. Current speed: 3.4 mb/s. 1017*1024: 1,041,408 mb 1,041,408 mb / 3.4 : 306,296 s 306,296 s / 60: 5104.94 min 5104.94 min / 60: 85.08 hours

as a rough estimate seems about right, but speed will fluctuate at different times. they have ~40mbps upload speed (as opposed to ~650 download) which is on the lower sides especially if they have remote users connect to the office. We already switched them to faster S3 storage type which reduces initial backup duration x5 times, but the tradeoff it does use more bandwidth. They need to check with ISP what upload speed is on their current plan and if the ISP offers next tier to increase bandwidth

thanks a lot Alex

# Resolve slow remote connections during large Nova Backup operations

## Problem

A client office experienced persistent remote connection issues while Nova Backup was running daily scheduled backups. The office had recently upgraded their server, requiring a full backup of over 1TB of data. With an upload speed of approximately 40mbps (~3.4 MB/s actual throughput), the initial backup was consuming significant bandwidth and causing connection problems for remote users. The backup was estimated to take approximately 85 hours to complete at current speeds.

## Resolution

1. **Verify the backup type**: After server upgrades, Nova Backup must perform a complete full backup before reverting to incremental daily backups that take only minutes
2. **Calculate completion timeline**: Use the formula `(Pending GB × 1024) ÷ Current Speed MB/s ÷ 3600` to estimate hours remaining
3. **Check current internet plan**: Contact the ISP to verify upload speeds on the current plan - download speeds are typically much higher than upload speeds
4. **Consider bandwidth upgrade**: For offices with remote users, upload speeds below 40mbps may be insufficient during large backup operations
5. **Optimize backup storage**: Switch to faster S3 storage type if available, which reduces backup duration by approximately 5x but uses more bandwidth
6. **Plan for completion**: Allow the initial backup to complete (estimated timeline based on calculation), after which daily incremental backups will resume normal operation

The office should contact their ISP about upgrading to the next tier for increased upload bandwidth to prevent future issues with large backups and remote user connectivity.
