Previously we were running all our backup to NTFS with deduplication. But we have had a few problems with NTFS and deduplication where we run into NTFS limits and defragmentation and need to restart the backup job. This was with v8 with one file per job. We also had a few restores from the NTFS where deduplication has caused the restore to take for ever.
My idea is:
- - Backup VM to ReFS storage for fast restore. Retention for about 14 - 30 days. This is the primary backup server.
- Backup the same VM to another server for long time rentention. 1 year with syntetic or active full ever 90 days. Using NTFS and deduplication.
Pros and cons with using this method instead of Backup Copy Jobs from the primary backup server?
