delolder fileset [/Keep:keepnumber] [/FreeDisk:freeDiskBytes] [/Age:Age]
[/Percent:PercentOfMax] [/Size:SizeInBytes] [/DeleteInv]
[/Test] [/?]
Fileset (*.BKF)
files to be deleted, use wildcards!
/Keep:keepnumber (/Keep:42)
At least this number of files will be kept regardless of any other criteria (except /DeleteInv)
/freeDiskBytes: # (/freeDiskBytes:200kB)
make this number of bytes (kb, GB) free on the disk.
The number of files specified in /Keep are kept at least!
Deletion starts with oldest files, files are not deleted if younger than specified in /Age.
Numbers are named according to IEC 1996 and can be:
bytes: e.g. 2048
Kilobyte: 2kb = 2.000 bytes
Kibibyte: 2KiB = 2.048 bytes
Megabyte: 2Mb = 2.000.000 bytes
Mebibyte: 2MiB = 2.097.152 bytes
Gigabyte: 2GB = 2.000.000.000 bytes
Gibibyte: 2GiB = 2.147.483.648 bytes
/Age:Age (/Age:2w)
only files that are older than that age are deleted. The age can be specified in:
Days: e.g. 14
Weeks: 14W
Months: 2M
Years: 2Y
/PercentOfMax:percent (/PercentOfMax:50)
Files smaller than this size are treated as invalid (see /DeleteInv)
/SizeInBytes:size (/SizeInBytes:50MB)
Files smaller than this size are treated invalid (see /DeleteInv)
/deleteInv
Invalid Files are deleted (otherwise they are ignored i.e. kept but not counted)
/test
Test-run, report actions without actually executing!
Is a good Idea to use that first!
Sample Use Cases:
You can delete all files older than a certain age, or just keep the newest 3 files.
You can delete files until a certain amount of harddisk space is available while keeping at least 1 file.
You can even judge if a file is valid by watching it's size. Sometimes the backup process creates a backup
but stop after 500MB. With the valid theshold of 500MB you can either skip or delete such files while preserving
older but valid files.
In my installations I used some batch files calling ntbackup to back up my customer's pc. I did not
want to overwrite the backup files since sometimes the backup process did not work completely, and produced
broken output.
The backup batch files produced something like "LABIS_backup_xxxxxxxx.bkf":
e.g.
04.09.2008 22:26 1.155.615.232 LABIS_backup_200809042200.bkf
11.09.2008 22:25 1.158.760.960 LABIS_backup_200809112200.bkf
18.09.2008 22:25 1.162.955.264 LABIS_backup_200809182200.bkf
25.09.2008 22:27 1.166.100.992 LABIS_backup_200809252200.bkf
02.10.2008 22:27 1.172.395.520 LABIS_backup_200810022200.bkf
09.10.2008 22:28 1.175.651.840 LABIS_backup_200810092200.bkf
So I was searching for something that deleted my old files, ensuring that at least 2 backup files was left
There is a rather old VBS script somewhere out there, but I was not able to get that running, and it was not
able to retain a number of files.
I decided to practice a little bit C# which means that delolder needs the .NET library (2.0).
In the example above, you can e.g. want to keep the files of the last 3 weeks but keep at least 3 files:
(please notice the testmode /test)
c:\backup>delolder /age:3w /keep:3 /test labis*.ful
SigiSoft DelOlder 1.00.03
Parameters:
Files:labis*.ful
/age:21 (=22.09.2008 15:43)
/test
5 to keep c:\backup\LABIS_backup_200810092200.ful
4 to keep c:\backup\LABIS_backup_200810022200.ful
3 to keep c:\backup\LABIS_backup_200809252200.ful
0 would have deleted c:\backup\LABIS_backup_200809042200.ful
1 would have deleted c:\backup\LABIS_backup_200809112200.ful
2 would have deleted c:\backup\LABIS_backup_200809182200.ful
DelOlder kept 3, would delete 3 and failed for 0 out of total 6 files
would delete 3,24GiB
If the backup failed for any reason at 2008/10/02 the file list might look this way:
04.09.2008 22:26 1.155.615.232 LABIS_backup_200809042200.bkf
11.09.2008 22:25 1.158.760.960 LABIS_backup_200809112200.bkf
18.09.2008 22:25 1.162.955.264 LABIS_backup_200809182200.bkf
25.09.2008 22:27 1.166.100.992 LABIS_backup_200809252200.bkf
02.10.2008 22:27 2 LABIS_backup_200810022200.bkf
09.10.2008 22:28 1.175.651.840 LABIS_backup_200810092200.bkf
If you want to keep at least 3 valid backup files, you can specify a minimum backup size (e.g.1gb):
you can specify the minimum size in gb, Mb, kb, bytes or GiB, MiB, KiB.
c:\backup>delolder /age:3w /test /keep:3 /size:1gb labis*.ful
SigiSoft DelOlder 1.00.03
Parameters:
Files:labis*.ful
/keep:3
/age:21 (=22.09.2008 16:05)
/size:953,68MiB
/test
5 to keep c:\backup\LABIS_backup_200810022200.ful
4ignored invalid file c:\backup\LABIS_backup_200810092200.ful
3 to keep c:\backup\LABIS_backup_200809252200.ful
2 to keep c:\backup\LABIS_backup_200809182200.ful
0 would have deleted c:\backup\LABIS_backup_200809042200.ful
1 would have deleted c:\backup\LABIS_backup_200809112200.ful
DelOlder kept 3, would delete 2 and failed for 0 out of total 6 files
1 invalid files
would delete 2,16GiB
You can also delete invalid files with /DeleteInv (Decide yourself if you want to automatically remove those files.)
