External hard disk(USB) for linux


Can anyone please suggest regard to extrenal hardisk as am new to linux.
which external hard disk can be bought (about 1 TB) to backup oracle database running on redhat linux into it.

I read some blogs that EHRD are based on ntfs filesystem and linux only supports hrd of format ext2,ext3,ext4.
Please tell which EHRD we can buy.
I think EHRD will be on ntfs format not ext3.
might also be fat32,fat16.

If we buy external harddisk of format ntfs file system, how can we mount, format it to ext3.
We already have these mount points

Thanks in advance

I think any external hard drive will be fine with Linux.

You can set up partitions and filesystems in the same way that you would with an internal drive----e.g. use fdisk, GParted, cfdisk, etc. to set up the partitions, and then use "mkfs" to create the filesystems.

I have three external USB hard drives from three different manufacturers (Seagate, Western Digital, and Fantom) and they all work flawlessly with Linux.

Note that, if your distro does not include NTFS drivers by default (and some, such as Debian, do not), you may need to get them, as most of these seem to come NTFS these days (in the olden days. when I was a young 'un, they tended to come FAT32).

Might even look at making it a LVM type to use.
