Subject: [Veritas-bu] [Incremental: (Differential + Cumulative)] + Full =
Backup Policy Question
I have a client that will be backing up a data set which:
=20
1) The client needs a full backup every 90 days with incrementals =
backups in between on a 1 year retention policy.
=20
I explained to the client that doing differential-incrementals would be =
a nightmare to do a full restore.
I then continued to explain that cumulative-incrementals would use a lot =
of tapes.
=20
I suggested the following:
=20
Day 0: Perform full backup.
Day 1: Perform differential-incremental.
Day 2: Perform differential-incremental.
Day 3: Perform differential-incremental.
Day 4: Perform differential-incremental.
Day 5: Perform differential-incremental.
Day 6: Perform differential-incremental.
Day 7: Perform cumulative-incremental. ***
Day 8: Perform differential-incremental.
Day 9: Perform differential-incremental.
Day 10: Perform differential-incremental.
Day 11: Perform differential-incremental.
Day 12: Perform differential-incremental.
Day 13: Perform differential-incremental.
Day 14: Perform cumulative-incremental. ***
Day 15: Perform differential-incremental.
Day 16: Perform differential-incremental.
Day 17: Perform differential-incremental.
Day 18: Perform differential-incremental.
Day 19: Perform differential-incremental.
Day 20: Perform differential-incremental.
Day 21: Perform cumulative-incremental. ***
Day 22: Perform differential-incremental.
Day 23: Perform differential-incremental.
Day 24: Perform differential-incremental.
Day 25: Perform differential-incremental.
Day 26: Perform differential-incremental.
Day 27: Perform differential-incremental.
Day 28: Perform cumulative-incremental. **
Day 29: Perform differential-incremental.
Day 30: Perform differential-incremental.
Day 31: Perform differential-incremental.
=20
Suppose at the end of the month the client wanted a FULL restoration of =
all files, by using this method tell me if this is correct:
=20
1) Restore Day 0's full backup.
2) Restore the cumulative backup from Day7, Day14, Day21,Day28.
3) Restore the differential-incremental backups from Day29,30,31.
=20
Then I would have fully restored all of the files, correct?
=20
Please let me know if this makes sense.
=20
Thanks!
=20
Justin.
