Do /hash and /usemd must be used for full backups only?
Posted: Fri Nov 30, 2018 8:49 am
Since I understand that using /hash and /usemd params may expose future restore to risk, when used improperly, I have read very careful the IFW manual. Still I am having big problem understanding the implications of using /hash and /usemd params.
Say I perform an initial _FULL_ backup of an entire disk using /hash /usemd on the command line. (Please note I am on Windows 7/10 *with* VSS)
Now, if I later want to perform subsequent _DIFFERENTIAL_ backups, must I include both /hash /usemd on the command line for the differential backups too? Or, for differential backups, I have to omit one or both of them?
I wil like to use *only* DIFFERENTIAL type of backups since, as stated on the IFW manual "Incremental backups are hard to properly manage and tend to be troublesome during disaster recovery."
Last, I need another clarification. In the IFW manual are explained the differencies between DIFFERENTIAL and INCREMENTAL backup types.
But I was not able to argue *how* can I specifically instruct IFW to perform a DIFFERENTIAL _OR_ INCREMENTAL backup. How does IFW infers the backup type it has to perform. Maybe two simple examples (DIFFERENTIAL and INCREMENTAL) may help me understand this topic.
My biggest fear is to setup a backup strategy and later discover that I cannot recover my data!
I suggest that section "Appendix B: Backup Strategies" is complemented with relative examples of the needed command line parameters to perform DIFFERENTIAL and INCREMENTAL backup types.
