Quality data ensures fast backups and restores, as well as reasonable on-disk storage. Low-quality data, on the other hand, is difficult to patch, which leads to slow backups and restores, with higher (i.e. more expensive) on-disk storage and bandwidth usage challenges.
We recommend adhering to the following backup selection best practices to maintain high data quality:
- Avoid including corrupted files in the backup selection.
- Avoid backing up already compressed files, or creating new compressed files from the same data sources.
- Avoid backing up databases in flat-file format.
- Avoid backing up data in encrypted format if the data changes daily.
- Wherever possible, use the same file names and locations for each backup or database dump.
