Backup files (archiving)

Question

Data archiving

Hello, tell me.
There is a file base of about 350 GB, I need their daily backup, I use 7zip.
When the archive was up to 160 GB, there were no problems, now the archive is more than 160 GB, the archiver makes the archive normal for the first time, beats it the second time (becomes unreadable).

Previously, I used WinRar, the problem arose when the archive file became more than 130 GB in size, switched to 7zip, now the same problem with it. I decided to make a multi-volume archive, now he writes after the first archiving that the file was not found.

What do you advise, what to do, can somehow change the script. It is necessary that the archive is supplemented!

script:
set PATHTO=G:
set FILEBACKUPNAME=backup

7z.exe u -w%PATHTO% -v20g %PATHTO%\%FILEBACKUPNAME% @listfiles.txt > %PATHTO%\%FILEBACKUPNAME%.log

Answer 1

I use tar+gzip (there should also be a version for Win)
archives large volumes (up to several terabytes) and there were no problems.

Answer 2

Use the backup utility from Acronis, it has no such problems.

Answer 3

check the RAM, maybe the problem is in the hardware

Answer 4

Try using the "no compression" compression level, sorry for the taftalogy.

Answer 5

Do you really need to back up 350GB every day? Or all the same all the files + changes per day?
But in fact - you are somehow preparing 7zip in a wrong way, he is perfectly able to make multi-volume books.
You can try Cobian Backup, we use it in many places, there are no complaints about the work, it can just do 7zip, and cut and make incremental / differential backups.

Answer 6

Stupid question, but is the latest version of 7z, and, most importantly, is it not a 32-bit system - maybe you have come across some non-obvious overflow bug?

Answer 7

I strongly advise in this case the free program Cobian Backup.
