Hi,

i have a lot of data backed-up with some DOS utility from 1991 to 1993. Every disk CONTAINS only one file PCBACKUP.00x (PCBACKUP.001, PCBACKUP.002, etc.) and NO other file. The names of the files led me to the Central POINT PC tools Backup utility, but it doesn't work. When i tried to make a test backup (with v6 a v9) the disks contains ANOTHER supplementary files (PCBACKUP.dir & PCBACKUP.inf) which looks like, that contains INFO about the original structure. Could some of you help me how to restore the backups?

The utility you need is most likely from MS-DOS 6.22 which was released about 1994.
That format might not be the same. What date is on the files?
The dates on the files are ranging from '91 to '93. Why do you guess that the utility is from MS-DOS 6.22?MS-DOS releases

Poprafka, you wrote on the Computing.net forum on June 29 that you had used MS-DOS 6.22 between 1991 and 1993. Since MS-DOS 6.22 was not released until April 1994, this is impossible.
I have used PCTOOLS v6 installed on MS-DOS 6.22 for a test backup ONLY, when i was trying to find out which software has been used to back up the data. Today I already know that it has been done USING the PCTOOLS v6 (i run it under MS-DOS 5), but i still can not open the backup backup archive without the supplementary files. Is it possible that the function of the same program is different running in different version of MS-DOS? ..i don't think soIf you do not have the catalog disk (the final disk of the set) yo cannot recover the backup.

hello poprafka.
I have the same problem with a PCBACKUP.001 file.
Please did you succeed to restore your file?
If yes, please tell me how you operated?
I thank you.

unfortunately I did not succeed, hope you'll have more luck. Please let me know, if you find a solution.

thanksHello poprafka
I succeed (a week job)
I use Central Point for windows R2 for win 3.1 with an old 486dx motherboard/cpu.
So it was not easy.
If you want, i can restore your floppy(s) before I throw all the old equipment.
Regards.

Hi beril,

that's great, congratulations! I' d be very happy if you could try to open also my data. I'll send it to you via PM.

thanks for help
