How can I view FSx for ONTAP snapshots?

I want to view snapshots for my Amazon FSx for NetApp ONTAP file system.

Resolution

There are two ways to view FSx for ONTAP snapshots:

  1. View snapshots from the client machine where you mounted the file system.
  2. View snapshots after you connect to the FSx for ONTAP file system through SSH.

View the snapshots from the client machine where you mounted the file system

1.    By default, snapshots are stored in the .snapshot directory at the volume root. Navigate to the directory where you mounted the file system, as shown in the following example:

$ ls -la /fsxfilesystem
total 12
drwxr-xr-x  4 root root 4096 Mar  8 07:21 .
dr-xr-xr-x 22 root root  309 Aug 12 08:10 ..
drwxrwxrwx 13 root root 4096 Aug 12 08:05 .snapshot
drwxr-xr-x  2 root root 4096 Mar  9 05:44 fsxvol

2.    To view the snapshots in the .snapshot directory, run the ls -la /fsxfilesystem/.snapshot command:

$ ls -la /fsxfilesystem/.snapshot
total 52
drwxrwxrwx 13 root root 4096 Aug 12 08:05 .
drwxr-xr-x  4 root root 4096 Mar  8 07:21 ..
drwxr-xr-x  4 root root 4096 Mar  8 07:21 backup-040db63a5fcf46442
drwxr-xr-x  4 root root 4096 Mar  8 07:21 daily.2023-08-11_0010
drwxr-xr-x  4 root root 4096 Mar  8 07:21 daily.2023-08-12_0010
drwxr-xr-x  4 root root 4096 Mar  8 07:21 hourly.2023-08-12_0305
drwxr-xr-x  4 root root 4096 Mar  8 07:21 hourly.2023-08-12_0405
drwxr-xr-x  4 root root 4096 Mar  8 07:21 hourly.2023-08-12_0505
drwxr-xr-x  4 root root 4096 Mar  8 07:21 hourly.2023-08-12_0605
drwxr-xr-x  4 root root 4096 Mar  8 07:21 hourly.2023-08-12_0705
drwxr-xr-x  4 root root 4096 Mar  8 07:21 hourly.2023-08-12_0805
drwxr-xr-x  4 root root 4096 Mar  8 07:21 weekly.2023-07-30_0015
drwxr-xr-x  4 root root 4096 Mar  8 07:21 weekly.2023-08-06_0015

NFSv4 mounted file systems

If you can't view the .snapshot directory in the ls -la /fsxfilesystem command output, then your file system might be mounted with Network File System (NFS) v4.

If your file system is mounted with NFSv4, then you don't see the .snapshot directory, as shown in the following example:

$ ls -la /fsxfilesystem
total 8
drwxr-xr-x 4 root root 4096 Mar 8 07:21 .
dr-xr-xr-x 22 root root 309 Aug 12 08:10 ..
drwxr-xr-x 2 root root 4096 Mar 9 05:44 fsxvol

List the snapshots using the ls -la /fsxfilesystem/.snapshot command:

$ ls -la /fsxfilesystem/.snapshot
total 52
drwxrwxrwx 13 root root 4096 Aug 12 08:05 .
drwxr-xr-x 4 root root 4096 Mar 8 07:21 ..
drwxr-xr-x 4 root root 4096 Mar 8 07:21 backup-040db63a5fcf46442
drwxr-xr-x 4 root root 4096 Mar 8 07:21 daily.2023-08-11_0010
drwxr-xr-x 4 root root 4096 Mar 8 07:21 daily.2023-08-12_0010
drwxr-xr-x 4 root root 4096 Mar 8 07:21 hourly.2023-08-12_0305
drwxr-xr-x 4 root root 4096 Mar 8 07:21 hourly.2023-08-12_0405
drwxr-xr-x 4 root root 4096 Mar 8 07:21 hourly.2023-08-12_0505
drwxr-xr-x 4 root root 4096 Mar 8 07:21 hourly.2023-08-12_0605
drwxr-xr-x 4 root root 4096 Mar 8 07:21 hourly.2023-08-12_0705
drwxr-xr-x 4 root root 4096 Mar 8 07:21 hourly.2023-08-12_0805
drwxr-xr-x 4 root root 4096 Mar 8 07:21 weekly.2023-07-30_0015

View snapshots after you connect to the FSx for ONTAP file system through SSH

1.    Connect to your file system through SSH. For more information, see Managing file systems with the NetApp ONTAP CLI.

2.    Run the following command:

FsxIdabcde::> volume snapshot show
