I have limited disk space and want to back up a few terra bytes of data, therefore I would like to implement the following backup schedule using scripts and would like to know the answers to the following questions:
Schedule:
1) First Saturday of each Quarter run a full backup
2) Every Saturday other than the First Saturday of each Quarter run an incremental backup
3) Every day other than saturday run a differential backup for the differences from the last incremental or full backup
I want to retain for long term keeping only the Full Backup and the Incremental backups; the differential backups I want to discard after 7 days
R-Drive Command Line
I've worked out the following command lines for my backups
1) For the full backup ->
Code: Select all
r-driveimagecl.exe create /a /o -s=C: -a="F:\Backups\C-Drive.arc" -r="C Drive Full Backup" -c=3 -u
Code: Select all
r-driveimagecl.exe append /a /o -append-inc -s=C: -a="F:\Backups\C-Drive.arc" -r="C Drive Incremental Backup" -c=3 -u
Code: Select all
r-driveimagecl.exe append /a /o -s=C: -a="F:\Backups\C-Drive.arc" -r="C Drive Differential Backup" -c=3 -u
Questions
a) Can I delete the differential backups without affecting the incremental or full backups?
b) How can I tell which backup files are the differential backup files compared to the incremental files; the files just have sequential suffixes and unless I open each one to read the comment it doesn't seem to be able to be automated, there is no command line switch to use a separate output file from the input file?
Many thanks in advance for any help
