Hi,
I'm trying to get a bat file that decides which kind of backup to do by comparing the sizes of the most recent full and differential backups.
This is what I am working with:
1) I store copies of my backups online. Due to my online storage provider's 2GB file size upload limit, I use Cobian Backup's ability to set a max size for each backup zip file so it automatically spans backups across multiple zip files. I end up with 5-10 2GB zip files for a full backup.
2) Cobian Backup names their backups the same way whether it is a full or differential backup. They advise using their log to tell which is which. The only way to tell which is which is to look at their the size, so I put fulls into a folder called Fulls and differentials into a folder called Diffs.
3) Cobian names the files "SourceFolder yyyy-MM-dd hh;mm;ss.zip" then the spanned files' extensions begin .z01, .z02, etc. with the same filename as the original.
I want the bat file to do differential backups until they reach 50% of the size of a full, then do a full instead. This is what I've go so far, but it only gets the size of one file into a variable so there's still a long way to go...
set filepath=c:\
set filename=testfile
set fileextension=.txt
dir /-c "%filepath%%filename%%fileextension%" | find "%filename%%fileextension%" > c:\temp.txt
for /f "tokens=1,2,3,4,5 delims= " %%i in ('type c:\temp.txt') do (set size=%%l)
echo The size of %filepath%%filename%%fileextension% is %size% bytes
pause
I have WIndows XP. Thank you for your help.
